高手请高手请进(刚性体穿透软组织)
我用的是不锈钢材料对软组织初步分析是用mooney-rivlin橡胶材料,建模和分网应该没有问题,接触分析是仿照子弹穿透混凝土作的,软组织采用的是SHELL163但是计算时显示要几千小时请高手指点是哪有问题。其中SHELL设置 和侵蚀算法 以及刚性体定义 和初始力加载应该有很多说法
请高手指点针对这个问题应该注意什么问题,小弟是新手 不胜感激!
有请版主和各位高手进不胜感激(附K文件)!!!
刚体对软体的侵彻请高手指点参数设置哪有问题,怎么需要这么长时间一百多小时其中接触算法和SHELL单元应该有很多问题,单位是mm n s 请高人指点,小弟是新手不胜感激!

[ 本帖最后由 zhtd2004 于 2007-9-22 00:02 编辑 ] 单元已经很少了,只有一千多个,怎么刚体对软体侵蚀需要这么长时间,、除了质量缩放和子循环需要如何设置参数能缩短求解时间呢? 请高人指点!!!
[ 本帖最后由 zhtd2004 于 2007-9-24 11:36 编辑 ] 请问钢与橡胶接触之间的静摩擦系数是多少?铜和橡胶呢
