模型出了问题,请教。
继续提问:我建模计算时遇到问题“Invalid default material model for element group 3.”
“element group 3”我是定义CFRP 筋的,也就是说FRP筋的材料定义出了问题。
我的材料定义是这样的:(a为轴向)
弹模Ea= 168900MPa b=c=10300MPa
泊松比为 ab=0.27ac=0.27 bc=0.02
代入公式算得剪切模量Gab=66496MPaac=4055MPa bc=5049MPa
请教哪里出了问题?

Here is the fix. 谢谢“tonnyw ”
我知道哪里里错了。我自己改改看。谢谢你。 错误改变了。。。 ***WARNING: No concentrated loads generated at point 112

提示:1 集中力没有加到FRP筋的端点上。
2 element group 3默认的材料模型无效。
再次请教。。。 问题继续.
solid实体建模,中间的一根筋材,我用的native画的线,是line-1,想用truss单元定义rebar。
最终在MESH的时候,实体可以划分,但meshline划分是line-1时候提示错误:
Can't use GLINE to generatedrebar element for TRUSS element3. 问题解决了,这种非线性材料的筋材,可以实体建模,定义接触。原来的native,solid 两种建模方式不兼容,不可以直接求解的。(需要额外的粘结处理)
