本文提出了一种高效和有效的数值分析技术预测焊接诱导屈曲。该技术将三维结构分析与二维焊接模拟相结合。该技术的实施可以确定不超过设计临界屈曲载荷的适当焊接条件。从小型和大型实体模型面板获得的实验结果被用来确认的分析模型的预测。最后，本文研究了热输入（焊缝尺寸）、壁板尺寸和壁板厚度对屈曲变形的影响。
This paper presents an efficient and effective numerical analysis technique for predicting welding-induced buckling. The technique combines three-dimensional structural analyses with two-dimensional welding simulations. Implementation of the technique can determine the appropriate welding conditions under which the design critical buckling load is not exceeded. Experimental results obtained from small- and large-scale mock-up panels are used to confirm the predictions of the analytical models. The paper concludes with a study of the effects of heat input (weld size), panel size, and panel thickness on buckling distortion.
