Small Punch Test for Ultrahigh Molecular Weight Polyethylene

Application ID: 115381


Ultrahigh Molecular Weight (UHMW) Polyethylene is a material commonly employed in knee and hip joint replacements. The “small punch test” is designed to assess mechanical properties using very small samples, such that because of their size they can directly be explanted. This example demonstrates the use of the Bergstrom-Bischoff material model in the Polymer Viscoplasticity feature available in the Nonlinear Structural Materials Module.

This model example illustrates applications of this type that would nominally be built using the following products:
