复合材料层合板壳热弹性动力响应

THERMOMECHANICAL DYNAMIC RESPONSE OF LAMINATED COMPOSITE PLATES AND SHELLS

本文提出了一个复合材料层合扁壳的位移场。据此导出了在力载和热载作用下的板壳运动方程。该位移场满足层间位移和横向剪应力的连续性，较充分反映了横向剪切对层合板壳力学行为的影响，但位移场的变量和运动方程均为五个，与一阶剪切变形理论相同。文中以暂态响应为例考察了横向剪切变形对层合板壳动力响应的影响，显著改善了解的精度。

A displacement field of laminated composite plates and shells is presented and used to establish the motion equations of laminates subjected to mechanical loading and thermal loading. The displacement field ensures the continuity of displacements and transverse shear stresses at each interface and includes the influence of transverse shear deformation on the response of laminates. The number of displacement variables and motion equations is five as in the first order shear deformation theory. Examples of transient response are given to verify the accuracy of the present method.
