Hiya guys,

I'm analysis my results for 1-D compression simulation and I faced a big question because the results for linear contact model is more accurate than the Hertz contact model. However, some researchers stated that there is no difference between the linear and non-linear results. Hence, I need to prove why the linear contact model, with all its weaknesses, simulates the experiment better than the more advanced nonlinear model?

Could you please help me to solve this issue?


Cheers
Sam
