  • an extended cell based smoothed three node Mindlin plate element xcs min3 for free vibration analysis of cracked fgm Plates
    International Journal of Computational Methods, 2017
    Co-Authors: T Nguyenthoi, Timon Rabczuk, V Hohuu, H Dangtrung, L Leanh, T Voduy
    Abstract:

    A cell-based smoothed three-node Mindlin plate element (CS-MIN3) was recently proposed and proven to be robust for static and free vibration analyses of Mindlin Plates. The method improves significantly the accuracy of the solution due to softening effect of the cell-based strain smoothing technique. In addition, it is very flexible to apply for arbitrary complicated geometric domains due to using only three-node triangular elements which can be easily generated automatically. However so far, the CS-MIN3 has been only developed for isotropic material and for analyzing intact structures without possessing internal cracks. The paper hence tries to extend the CS-MIN3 by integrating itself with functionally graded material (FGM) and enriched functions of the extended finite element method (XFEM) to give a so-called extended cell-based smoothed three-node Mindlin plate (XCS-MIN3) for free vibration analysis of cracked FGM Plates. Three numerical examples with different conditions are solved and compared with previous published results to illustrate the accuracy and reliability of the XCS-MIN3 for free vibration analysis of cracked FGM Plates.

  • analyses of stiffened Plates resting on viscoelastic foundation subjected to a moving load by a cell based smoothed triangular plate element
    International Journal of Structural Stability and Dynamics, 2017
    Co-Authors: T Nguyenthoi, H Luongvan, H Dangtrung, Kok Keng Ang
    Abstract:

    A cell-based smoothed three-node Mindlin plate element (CS-MIN3) based on the first-order shear deformation theory (FSDT) was recently proposed for static and dynamic analyses of Mindlin Plates. The CS-MIN3 overcomes shear-locking phenomena and has a faster convergence compared with the original MIN3. In addition, the CS-MIN3 uses only three-node triangular elements that can be easily generated automatically for arbitrary complicated geometric domains. This paper extends the CS-MIN3 by integrating itself with the Timoshenko beam element to give a new stiffened plate element for static, free vibration and dynamic responses of stiffened Plates resting on viscoelastic foundation subjected to a moving load. The viscoelastic foundation is modeled by discrete springs and dampers, and the displacement compatible condition between the plate and the stiffener is imposed. Some benchmark numerical examples were performed to illustrate the good agreement of the CS-MIN3 results with those by other methods in the literature to illustrate its accuracy and reliability. In addition, some new numerical examples that consider the effects of stiffeners on the behaviors of plate resting on viscoelastic foundation are conducted. The results demonstrate the expected properties in which the deflection of the stiffened plate resting on viscoelastic foundation can be reduced significantly.

  • an upper bound limit analysis of Mindlin Plates using cs dsg3 method and second order cone programming
    Journal of Computational and Applied Mathematics, 2015
    Co-Authors: T Nguyenthoi, P Phungvan, M H Nguyenthoi, H Dangtrung
    Abstract:

    The paper presents a numerical procedure for kinematic limit analysis of Mindlin plate governed by von Mises criterion. The cell-based smoothed discrete shear gap method (CS-DSG3) is combined with a second-order cone optimization programming (SOCP) for determining the upper bound limit load of the Mindlin Plates. The limit analysis problem of Mindlin Plates is formulated by minimizing the dissipation power subjected to a set of constraints of boundary conditions and unitary external work. This minimization problem is then transformed into an explicit form suitable for the solution using the SOCP. The numerical results of some benchmark problems show that the proposal procedure can provide the reliable upper bound collapse multipliers for the Mindlin Plates. CS-DSG3 is combined with SOCP for determining upper bound limit load of Mindlin Plates.Limit analysis problem is transformed into an explicit form suitable for solution using SOCP and CS-DSG3.Numerical results show that CS-DSG3 is free of shear locking and can provide reliable upper bound collapse multipliers for Mindlin Plates.

    Computational Materials Science, 2015
    Co-Authors: T Nguyenthoi, P Phungvan, T Buixuan, Q Lieuxuan
    Abstract:

    Abstract A cell-based smoothed three-node Mindlin plate element (CS-FEM-MIN3) based on the first-order shear deformation theory (FSDT) was recently proposed for static and free vibration analyses of Mindlin Plates. In this paper, the CS-FEM-MIN3 is extended to geometrically nonlinear analysis of laminated composite Plates. The nonlinear formulation is based on the C 0 -type high-order shear deformation plate theory ( C 0 -HSDT) and the von Karman strains, which deal with small strains and moderate rotations. In the process of formulating the system stiffness matrix of the CS-FEM-MIN3, each triangular element will be divided into three sub-triangles, and in each sub-triangle, the MIN3 is used to compute the strains. Then the strain smoothing technique on whole the triangular element is used to smooth the strains on these three sub-triangles. The accuracy and reliability of the proposed method is verified by comparing its numerical solutions with those of available other numerical results.

    Abstract:

    SUMMARY A cell-based smoothed discrete shear gap method (CS-FEM-DSG3) based on the first-order shear deformation theory (FSDT) was recently proposed for static and dynamic analyses of Mindlin Plates. In this paper, the CS-FEM-DSG3 is extended to the C0-type higher-order shear deformation plate theory (C0-HSDT) and is incorporated with damping–spring systems for dynamic responses of Mindlin Plates on viscoelastic foundations subjected to a moving sprung vehicle.

    Co-Authors: P Phungvan, T Nguyenthoi, H Nguyenxuan, Loc V Tran
    Abstract:

    Abstract A cell-based smoothed discrete shear gap method (CS-DSG3) based on the first-order shear deformation theory was recently proposed for static and dynamics analyses of Mindlin Plates. In this paper, the CS-DSG3 is extended to the C0-type high-order shear deformation plate theory for the static and free vibration analyses of functionally graded Plates (FGPs). In the FGPs, the material properties are assumed to vary through the thickness by a simple power rule of the volume fractions of the constituents. In the static analysis, both thermal and mechanical loads are considered and a two-step procedure is performed including a step of analyzing the temperature field along the thickness of the plate and a step of analyzing the behavior of the plate subjected to both thermal and mechanical loads. The accuracy and reliability of the proposed method is verified by comparing its numerical solutions with those of other available numerical results.

    Co-Authors: P Phungvan, T Nguyenthoi, T Ledinh, H Nguyenxuan
    Abstract:

    The cell-based smoothed discrete shear gap method (CS-FEM-DSG3) using three-node triangular elements was recently proposed to improve the performance of the discrete shear gap method (DSG3) for static and free vibration analyses of isotropic Mindlin Plates. In this paper, the CS-FEM-DSG3 is further extended for static and free vibration analyses and dynamic control of composite Plates integrated with piezoelectric sensors and actuators. In the piezoelectric composite Plates, the electric potential is assumed to be a linear function through the thickness of each piezoelectric sublayer. A displacement and velocity feedback control algorithm is used for active control of the static deflection and the dynamic response of the Plates through closed loop control with bonded or embedded distributed piezoelectric sensors and actuators. The accuracy and reliability of the proposed method is verified by comparing its numerical solutions with those of other available numerical results.

  • a cell based smoothed discrete shear gap method using triangular elements for static and free vibration analyses of reissner Mindlin Plates
    International Journal for Numerical Methods in Engineering, 2012
    Co-Authors: T Nguyenthoi, P Phungvan, H Nguyenxuan, C Thaihoang
    Abstract:

    SUMMARY The cell-based strain smoothing technique is combined with discrete shear gap method using three-node triangular elements to give a so-called cell-based smoothed discrete shear gap method (CS-DSG3) for static and free vibration analyses of Reissner–Mindlin Plates. In the process of formulating the system stiffness matrix of the CS-DSG3, each triangular element will be divided into three subtriangles, and in each subtriangle, the stabilized discrete shear gap method is used to compute the strains and to avoid the transverse shear locking. Then the strain smoothing technique on whole the triangular element is used to smooth the strains on these three subtriangles. The numerical examples demonstrated that the CS-DSG3 is free of shear locking, passes the patch test, and shows four superior properties such as: (1) being a strong competitor to many existing three-node triangular plate elements in the static analysis; (2) can give high accurate solutions for problems with skew geometries in the static analysis; (3) can give high accurate solutions in free vibration analysis; and (4) can provide accurately the values of high frequencies of Plates by using only coarse meshes.

  • static free vibration and buckling analysis of laminated composite reissner Mindlin Plates using nurbs based isogeometric approach
    International Journal for Numerical Methods in Engineering, 2012
    Co-Authors: Chien H Thai, T Nguyenthoi, H Nguyenxuan, Nhon Nguyenthanh, Timon Rabczuk
    Abstract:

    SUMMARY This paper presents a novel numerical procedure based on the framework of isogeometric analysis for static, free vibration, and buckling analysis of laminated composite Plates using the first-order shear deformation theory. The isogeometric approach utilizes non-uniform rational B-splines to implement for the quadratic, cubic, and quartic elements. Shear locking problem still exists in the stiffness formulation, and hence, it can be significantly alleviated by a stabilization technique. Several numerical examples are presented to show the performance of the method, and the results obtained are compared with other available ones. Copyright © 2012 John Wiley & Sons, Ltd.
