摘要
采有奇异摄动法分析面内纵边可移简支和不可移简支两类边界条件下板格在面内轴向压缩下的极限强度，给出计及焊接残余变形和应力的有效宽度计算公式。
A singular perturbation method has been developed in order to analyze the ultimate strength of plating under two inplane boundary conditions.The effective breadth of plating has been formulated analytically which can take the residual stress and deformations into account.It shows that the proposed method is of good accuracy and efficiency,compared with nonlinear finite element method.
