竞争对手卖同样的东西,但是贵很多. IT 买了我的东西后,email我说我的东西状况非常
差,不应该卖.我卖的是brand new, 打包非常好.IT claim 不是运输时候损坏的.我
offer full refund,but IT refuse to mail it back, and leave a very bad
feedback,说我是骗子. 请各位大牛支招如何remove negative feedback or do the
same thing to it. 如有好主意,包子奉送.
IT email me now:

用 LS-DYNA 里面就有好几个橡胶的模型,前处理软件ls-prepost里面直接就可以用了
,不需要自己写UMAT;模型的参数可以在ANSYS的帮助文件里面找到。
如果需要弄懂模型的原理,请看这篇文章,很详细:
