Overview of Available Modeling and Simulation Techniques

Any FE analysis requires the input of appropriate geometry, loading conditions, and material behavior. Key to the development of any material model is good data from the laboratory describing the candidate material s behavior under some set 

Summary of Available Modeling Approaches and Techniques for Predicting the Behavior of UHMWPE 

Handbook solution (using a linear elastic material model) Fast and easy to perform Simple geometries only Does not consider nonlinearity material behavior Only for very small strains May give inaccurate results 

Closed-form analytical solution (using an isotropic plastic material model) Fast and easy to perform More accurate than a linear elastic solution Handbook solutions are available only for very few geometries and loading conditions May give inaccurate results 

FE analysis using a simple material model (e.g., linear elastic, hyperelastic, linear viscoelastic, isotropic plasticity) Can account for complex geometries Relatively easy to perform Does not consider the true material behavior in general deformation states Typically valid only for small-intermediate deformations May give inaccurate results
