(RILEM)应力—应变曲线问题
The International Union of Laboratories and Experts in Construction Materials(简称为RILEM)提供的应力-应变曲线实测方法中,有几个关键参数:the strain hardening point "εst",the uniform strain "εuni",the ultimate strain "εu",the strain hardening modulus Est,是怎么定义的,有没有国外同行或做过类似工作的同盟,请画一个曲线图示意一下。[ 本帖最后由 jzhang2007 于 2008-12-7 12:07 编辑 ]
