Defining nonlinear material properties in ANSYS workbench

  I can define the properties of materials in ANSYS workbench. However, if my material is nonlinear, do I need to define anything extra? Generally I put density, poison ratio and young's modulus to define the material properties.

  Yes, you drag and drop the needed nonlinear model from the Toolbox onto your material, then enter the material constants that model needs. The list of nonlinear models is grouped into types. I have expanded the Hyperelastic and Plasticity models, but there are many more. The challenge is obtaining the correct experimental data for the material constants and coefficients.

  How can we find material constants and coefficients ? could you please show what exactly you mean?
  
  thank you
