How to assign PMMA and PEEK material in abaqus? I want to model calcaneal prosthesis using PMMA and PEEK.0
 
First you have to create two separate materials with elastic properties like these:
- PMMA: E = 3 GPa, ν = 0.35
- PEEK: E = 3.6 GPa, ν = 0.4

Then create two sections with these materials and assign them to your model.
 
Isn't PMMA a polymer and hyperelastic?
 
Polymers are often modeled using linear elastic behavior. Especially when you don't have necessary data for more advanced non-linear material models. It all depends on requirements for the analysis.
