中文摘要 | 銲接製程導致的變形及殘留應力問題始終困擾著銲接工程人員,而隨著電腦硬體設備及軟體發展逐漸成熟,以有限元素分析法來作數 值模擬複雜的銲接問題漸趨可行。本文介紹如何以有限元素分析法來模擬銲接製程,包括銲接製程之物理現象、分析技巧及簡化技巧等,同時 介紹板材結構之二維平面應力、二維平面應變及三維分析實例,其結果與理論趨勢吻合。 。 |
英文摘要 | The welding distortions and residual stresses are always serious problems in welding engineering. Simulating the welding process with F.E.M. analysis becomes more and more possible as the computer hardware and software are developed more and more completely. This article will introduce the tricks of analysis and simplification. The case studies of F.E.M. analysis in welded plate structure by 2-dimensional plane stress analysis, 2-dimensional plane strain analysis and 3-dimensional solid analysis are also presented in this article. It is showed that the results of F.E.M. analysis match the theoretical trend and practical experiences iences |
