Non linear property for Material

trithanh221

Hi all,

I have the question that can we apply non-linear property for Materia ? And how to apply if can.

Thank you guys so much.

Thanh.

For example,

After testing the rock we have the non-linear data about Young's modulus and poisson's ratio. So, i need to input that curve of data to the model of rock sample. Can we do that on Mecway and how to do that.

Thank you,
Thanh.

You can define a nonlinear stress-strain curve by entering the CCX cards under CCX -> custom model definition. There's an example of that in the manual section 14.1 Custom model definition.

I don't know about nonlinear Poisson's ratio. There are other nonlinear materials available in CCX though like creep so maybe one of them will be more suitable.
