Abstract

This paper will expand the third-order shear deformation theory by the double-Fourier series and reduce to the solution of a system of ordinary differential equations in time, which are integrated numerically using Newmark's direct integration method and clarify the undamped dynamic responses for the cross-ply and antisymmetric angle-ply laminated composite plates and shells with simply supported boundary condition. Numerical results for deflections are presented showing the effect of side-to-thickness ratio, aspect ratio, material anisotropy, and lamination scheme.

본 연구에서는 복합재료로 구성된 복합적층판 및 쉘에 대하여 3차 전단 변형이론을 이용한 변위를 가정하여 단순지지 경계조건을 만족하는 변위형상함수를 퓨리예급수로 전개하고 동적 평형 방정식을 유도하여 뉴마크의 수치적분법을 사용하여 단면특성계수, 재료의 특성, 층의 배열에 따른 복합적층판 및 쉘의 비감쇄 동적응답특성을 연구하였다.
