a cell based smoothed finite element method using three node shear locking free mindlin plate element cs fem min3 for dynamic response of laminated composite plates on viscoelastic foundation
Engineering Analysis With Boundary Elements, 2014Co-Authors: H Luongvan, T Nguyenthoi, G R Liu, P PhungvanAbstract:Abstract A cell-based smoothed finite element method using three-node Mindlin plate element (CS-FEM-MIN3) 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-MIN3 is extended and incorporated with damping-spring systems for dynamic responses of sandwich and laminated composite plates resting on viscoelastic foundation subjected to a Moving Mass. The plate-foundation system is modeled as a discretization of three-node triangular plate elements supported by discrete springs and dashpots at the nodal points representing the viscoelastic foundation. The position of the Moving Mass with specified velocity on triangular elements at any time is defined, and then the Moving Mass is transformed into loads at nodes of elements. The accuracy and reliability of the proposed method is verified by comparing its numerical solutions with those of others available numerical results. A parametric examination is also conducted to determine the effects of various parameters on the dynamic response of the plates on the viscoelastic foundation subjected to a Moving Mass.

new semi analytical solution for a uniformly Moving Mass on a beam on a two parameter visco elastic foundation
International Journal of Mechanical Sciences, 2017Co-Authors: Zuzana DimitrovovaAbstract:Abstract In this paper a new semi-analytical solution for the Moving Mass problem is presented. Firstly, the problem of a Mass traversing a finite beam on an elastic foundation is reviewed and some new aspects are added. Then, the new semi-analytical solution is deduced for an infinite beam. The semi-analytical solution of the displacement under the Mass is derived with the help of integral transforms and the full deflection shape is obtained by linking together two semi-infinite beams. An iterative procedure is suggested for the determination of the frequency of the oscillation induced by the Moving Mass. Results deduced for infinite beams are confirmed by analysis of long finite beams, with the help of derivations given in the first part of this paper. Convergence analysis on finite beams is also presented, and, in addition, the effects of the normal force, of the harmonic component of the vertical force and of the foundation damping are discussed.

new semi analytical solution for a Moving Mass problem the effect of initial conditions and abrupt change in foundation stiffness
Procedia Engineering, 2017Co-Authors: Zuzana DimitrovovaAbstract:Abstract In this contribution, the new semi-analytical solution for the Moving Mass problem from [1] is extended to account for the influence of initial conditions. The essential part of the new closed-form formula derived in [1] is the term governed by the Mass-induced frequencies, which cannot be obtained when a common solution method for this kind of problems like double Fourier transform is used. Apart the term given by the closed-form formula, there is a transient part of natural vibrations originated by a line discontinuity in the Laplace image of the displacement under the load. Analytical expression is derived for such a defined line cut. Then the transient part is determined by numerical integration and added to the response given by the closed-form formula. Very good coincidence between results on finite and infinite beams is obtained, which is further exploited for the analysis of the influence of the abrupt change in the foundation stiffness.
