这是一个柔性机械手抓,在一侧同期可以进行弯曲从而抓取,想用硅橡胶这种材料进行,在做硅橡胶这种材料分析的时候,错误为

The initial bulk modulus of 2.01037e+08 exceeds 100 times the initial shear modulus of 3.77697e+05 (the initial poisson ratio 0.49906 exceeds 0.495) for the hyperelastic material named rubber. However, a hybrid type element is not used. This may cause convergence problems. It is recommended that you change the element type to a hybrid element; however you can also convert this error message to a warning message by setting the environment variable nonhybrid_incompress to warning or by adding *diagnostics, nonhybrid=warning to the input file (not recommended).

Analysis Input File Processor exited with an error.

我的参数都是在abaqus帮助文档找到的,不知道是不是材料的原因,真的很烦恼,谢谢各路大神帮助,如果有想试试的我也可以发模型,谢谢大神

不是真正的工程师
参数不对,弹性模量 泊松比和剪切模量之间是有一定数量关系

不是真正的工程师
给定模量和泊松比,剪切模量是定的,三者应该是协调的,我的理论懂得也不太多
