Area of Science:

Computational mechanics
Finite element analysis
Surgical simulation

Background:

Fast finite element solutions require low-order elements like linear tetrahedrons.
Standard linear tetrahedral elements suffer from volumetric locking with nearly incompressible materials.
Automatic hexahedral meshing for complex geometries is difficult, necessitating tetrahedral or mixed meshes.

Purpose of the Study:

To extend the average nodal pressure tetrahedral element for improved handling of multiple material interfaces.
To enhance accuracy and computational efficiency in surgical simulations involving complex material behaviors.

Main Methods:

Extension of the average nodal pressure (ANP) tetrahedral element formulation.
Integration of the new element into a Total Lagrangian Explicit Dynamics (TLED) algorithm.
Comparative performance evaluation against the standard ANP element.

Main Results:

The enhanced element uniformly handles multiple materials with improved accuracy.
Volumetric locking is mitigated in simulations with nearly incompressible materials.
The modified TLED algorithm efficiently supports the new element formulation.

Conclusions:

The developed tetrahedral element offers superior performance for surgical simulations with multiple materials.
Accurate prediction of reaction forces and displacements is achieved.
The formulation presents a computationally efficient advancement in finite element methods.
