Hi Aslinn,

Ah, so the material you defined is an isotropic elastic material since you only defined Young's modulus and Poisson's ratio, and in this case, your model will only behavior linearly. 

So to solve the issue you will need to find the correct material properties, maybe adding some damage or as least hardening to the material (these are just suggestions based on my initial impression). I would recommend referring to the test data or literature to determine the best material properties to use.
