怎样在ls-dyna软件中输入泡沫铝的应力应变曲线

请教下63号材料中的拉伸截断应力TSC参数的意义和取值，是指抗拉强度么？一般取平台应力的多少呢？

泡沫铝用mat63就可以了。

我也在做类似的例子，请问泡沫铝是怎么仿真的？望回复，谢谢！

您好 请问选择哪个材料模型啊 有的模型不支持定义应力应变曲线

这个问题我现在可以解答 。算作给后来人解答吧哈哈。
1、首先你要建立或者导入一条材料的应力应变曲线。
2、接着在材料卡片中编辑，LCID项激活点击进去选择上面建立的曲线即可。
* 至于曲线如何建立，就是另外一个问题了。

楼主你好，我现在做这方面的工作，不知可否加你好友向你请教下？

直接在HM中定义很简单

哪位大哥帮忙看一下啊

麻烦楼上的高手帮忙看下我的k文件吧，怎样在k文件里面定义泡沫铝的应力应变曲线啊。
