摘要
采用非线性有限元直接计算方法,对系列加筋板在轴向压力下的极限强度进行了计算分析.大量数值计算结果与Smith及Tanaka的实验结果进行了验证.基于有限元分析结果,提出了加筋板极限强度的预报公式.文中公式与有限元计算及实验对比结果表明,所提出的公式具有较高的精度.
Ultimate strength analyses have been performed by Non linear FEM to a series of stiffened plates subjected to longitudinal compression.The numerical results from non-linear FEM are validated with Smith and Tanaka experiments.A proposed formula is presented for the ultimate strength prediction of stiffened plates.The formula is in good agreement with a large number of FEM calculations and experiment results.
