Abstract

The transient analysis of partially supported laminated plates with rectangular holes under uniformly distributed transverse load is studied using finite element method. The first-order shear deformation theory and the variational energy method are employed in mathematical formulation. The effects on central deflection by plate thickness ratio, material modulus ratio, ply lamination geometry and boundary conditions are investigated Numerical results are presented and comparisons of the results by the present method with those given in the literature are made.

본 연구에서는 부분지지되어 있고 사각형의 개구부를 갖는 적층복합판의 과도해석을 유한요소법을 이용하여 연구하였다. 수학적 지배방정식은 변분과 일차전단변형이론을 고려하여 유도하였고 적층판의 폭-두께비, 재료의 특성, 적층각도, 지지조건이 중앙점의 동적응답에 미치는 영향에 대하여 연구하였다. 수치적인 결과는 그래프와 표로 나타내었으며 참고문헌의 결과와 비교 분석하였다.
