  • Control of transient thermoelastic displacement of an Angle-Ply Laminated cylindrical panel bonded to a piezoelectric layer
    Applied Mathematics and Computation, 2004
    Co-Authors: Yoshihiro Ootao, Yoshinobu Tanigawa

    Abstract:

    In this study, the theoretical analysis of a control of transient thermoelastic displacement is developed for an Angle-Ply Laminated cylindrical panel bonded to a piezoelectric layer due to nonuniform heat supply. By using the exact solutions for Angle-Ply Laminate and piezoelectric layer of crystal class mm2, the theoretical analysis of a transient piezothermoelasticity is developed for a simply supported cylindrical composite panel under the state of generalized plane deformation. Analysis of a piezothermoelastic problem leads to an appropriate electric potential applied to the piezoelectric layer which suppresses the induced thermoelastic displacement in the radial direction at the midpoint on the free surface of the Angle-Ply Laminate. Some numerical results for the temperature change, the displacement, the stress in a transient state when the transient thermoelastic displacement is controlled are shown in figures.

  • analysis of transient thermal stress and thermal deformation of an angle ply Laminated rectangular plate due to nonuniform heat supply based on higher order shear deformation theory
    JSME international journal. Series A mechanics and material engineering, 1996
    Co-Authors: Yoshinobu Tanigawa, Kazuki Nagayama, Ryuusuke Kawamura

    Abstract:

    This article concerns a theoretical analysis of heat conduction in a transient state and the associated thermoelastic behavior for a multilayered anisotropic Laminated plate subjected to nonuniform heat supply. As an analytical model, we consider a Laminated rectangular plate consisting of a diagonal stack of layers having orthotropic material properties, i.e., an Angle-Ply Laminate. The three-dimensional temperature solution in a transient state and the associated thermoelastic behavior of the plate with simply supported edge conditions are formulated using the functional approach based on the variational principle. For the analysis of the thermoelastic field, the higher-order shear deformation theory of the plate is used to evaluate the shear stress components. As an example, numerical calculations are carried out for a 2 layered Angle-Ply Laminate, and the numerical results for temperature distribution, out-of-plane deflection, normal and shear stress distributions are discussed in detail.

  • transient thermal stress and thermal deformation of an angle ply Laminated rectangular plate due to nonuniform heat supply based on higher order shear deformation theory
    Transactions of the Japan Society of Mechanical Engineers. A, 1995
    Co-Authors: Yoshinobu Tanigawa, Kazuki Nagayama, Ryuusuke Kawamura

    Abstract:

    This paper is concerned with a theoretical treatment of thermal stress and thermal bending problems for a multi-layered anisotropic Laminated plate due to partially distributed heat supply. As an analytical model, we consider a Laminated rectangular plate consisting of a diagonal pile of layers having orthotropic material properties, i. e. an Angle-Ply Laminate. We obtain the three-dimensional temperature in a transient state and thermal deformation of a simply supported plate using the higher-order shear deformation theory. As an example, numerical calculations are carried out for a 2-layered Angle-Ply Laminate, and the numerical results are examined precisely.

  • analysis of thermal stress and deformation due to nonuniform heat supply in an angle ply Laminated rectangular plate
    Transactions of the Japan Society of Mechanical Engineers. A, 1995
    Co-Authors: Yoshinobu Tanigawa, Ryuusuke Kawamura, Tomohiro Takahara, Kazuki Nagayama

    Abstract:

    This paper describes theoretical treatment of problems of thermal stress and thermal bending due to partially distributed heat supply for a multilayered anisotropic Laminated plate. As an analytical model, we consider a Laminated rectangular plate consisting of a diagonal stack of layers having orthotropic material properties, i. e. an Angle-Ply Laminate. Introducing the Rayleigh-Ritz method based on the variational principle, a three-dimensional temperature solution for a transient state is given. Moreover, for the thermoelastic problems, the components of displacements are analyzed using the Rayleigh-Ritz method, and the characteristic behaviors of thermal stress and thermal deformation for a simply supported plate are determined. As an example, calculations are carried out for a 2-layered Angle-Ply Laminate, and the results are examined precisely.

  • stiffness degradation resulting from 90 ply cracking in angle ply composite Laminates
    Composites Science and Technology, 1999
    Co-Authors: B. Pradhan, Venu N Kumar

    Abstract:

    Abstract Stiffness degradation resulting from 90° ply cracking in [±θn/90m]s Angle-Ply composite Laminates has been evaluated by a 3D finite-element method. A control volume having a single simulated transverse crack in 90° ply/plies and intact ±θ outer layers is used for the analysis. The stiffness degradation as a transverse crack extends in the width direction for glass/epoxy Angle-Ply Laminates is calculated for different crack lengths and different fibre orientation angles θ of the outer layers. Effects of the number of 90° layers and number of ±θ layers on the Laminate stiffness have also been studied. It has been observed that the available stiffness of the cracked Angle-Ply Laminate largely depends on the fibre orientation angle of the outer layers, the number of cracked cross-ply layers and the number of uncracked outer ±θ layers in the Laminate.
