Buckling Analysis of Composite Cylindrical Panels under Combined Loading of Constant Lateral Pressure and Incremental Compression

일정 횡하중과 증분 압축하중을 동시에 받는 복합적층 판넬의 좌굴 해석

This paper addresses a modified arc-length method for the nonlinear finite element analysis of a structure which is loaded in incremental and fixed forces, simultaneously. The main idea of the method is to separate the displacement term by the constant force from that by the incremental force. As the illustrative examples of the applicability of the present algorithm, a parametric study is performed on the nonlinear buckling behavior of composite cylindrical panels under the combined load of the incremented compression and the constant lateral pressure.
