如何建裂纹模型和网格划分

如何在胶接接头胶粘剂中建裂纹模型和网格划分？

lowkey2003 发表于 2007-4-23 22:47

看这个能表示裂纹吗？

网格要在裂纹尖端细化

lowkey2003 发表于 2007-4-24 11:18

那个尖端奇异性如何表示了?

那个尖端奇异性如何表示了?用KSCON命令,可以吗?还有,KSCON 参数如何设置适合?
我的胶层厚度为0.12mm,网格划4层，采用三角形自由划分。
谢谢解答！！

求助：复合材料胶接问题

胶的特性是怎么定义的呢？
能说说么？

lowkey2003 发表于 2007-5-10 13:56

看这能帮到你不？

你是问材料属性还是什么？
！定义材料属性
