Combined Nonlinear Analysis of Compressed Plate
Abstract
初期 처짐을 가진 단순지지된 평판이 일축 압축을 받을 때의 非線型 解析을 遂行하기 위하여 增分形 有限帶板法을 公式化하고 이에 따라 전산 프로그램을 작성하였다.

curvature effect를 고려하여 面外變位函數로부터 유도한 식을 참고로 하여 새로운 面外變位函數를 가정하였다.

外力을 가하는 方法으로 荷重增分 方式과 變位增分 方式을 使用하여 계산한 결과 變位增分 方式이 荷重增分 方式보다 수렴이 빨랐으며, 새로운 變位函數를 使用한 有限帶板法은 해석적 방법이나 다른 有限要素法과 잘 일치하는 결과를 주었다.
For the finite deflection analysis plates and stiffened plates with initial deflections subjected to uniaxial compression, the formulation of incremental finite strop method is made and has been incorporated into a computer program.

A new in-plane displacement function varying along the load direction has been derived from the out-of-plane displacement function by considering the curvature effect of a plate.

The following results halve been obtained:

1. Incremental displacement type analysis is superior to incremental load type analysis in that the former converges more rapidly than the latter.

2. The finite strip method using the new displacement function gives as accurate results as analytical method and other finite element method.
