non convergence in hyperelastic model for heavy loads

Please login with a confirmed email address before reporting spam

Thanks for the fruitful information.

I am facing an issue with nonconvergence of nearly bat 30kPa while applying compressive load up to 300kPa on ecoflex 0030 material. Nonlinear solid mechanics has been used with different hyperelastic models such as mooney rivlin 20 parameters, odgen, and neo Hookean. Can somebody help me with the issue of finding out the probable reason behind nonconvergence?

Note its a 2D block of 5mm by 2mm made of ecoflex 0030.

Also, do this problem need to be solved with moving mesh? I am facing a problem with moving the mesh as I am unable to describe/utilize it properly.
