Hello Everyone,
I am simulating contact of a sphere with a soft elastomer (Hertz contact). Unlike the hertz contact, I will like to simulate large deformations. My model is a 2D axisymmetric model and the load is displacement controlled. The current model fails at total time/freq ~ 0.84. I have tried refining my mesh and have reduced the increment size and increased the number of increments. Currently, step my parameters are:
Max. number of increments: 200000 and Increment size:0.005/1E-5/0.01
Nlgeom is On because of the large deformation.
Please, does anyone know why the model is not running to completion? I will greatly appreciate any suggestion.
Thank you.
Uyi
>> I have attached the inp file. I am only simulating the loading step in this case.
