摘要
本文以五万米~3油罐大角焊缝为例,列举了以侧角(θ)为控制参数的五种形状的角焊缝模型。应用平面弹塑性有限单元法算出其应力分布情况;又算出了这五种形状角焊缝趾端部和焊肉中央处的表面裂纹疲劳断裂的寿命。同有关文献结果作了比较。
Five different shapes of fillet weld joint models are listed, using flank angle as the main controlling factor, The states of stress of these models are obtained by applying the elasto-plastic finite element method. The fatigue life of the surface cracks of the weld toe and the central part of the welding bead are calculated. A comparative study of the results obtained is made with those seen in relevant literature, and some conclusions useful to the designing of fillet weld joints of cylindrical oil storage tank, are derived.
