Multi-body Contact Analysis Technical Brief
Abstract: A multi-body contact capability has been implemented to account for frictionless mechanical contact that does not require mesh conformity in the contact regions. The implementation is available for Planar, Extrusion, Axisymmetric and 3D elasticity problems. Material nonlinearities of the contacting bodies can be considered in the analysis. The effect of geometric nonlinearities (large strains, large rotations) are not yet available but will be addressed in a later release.

“Of the three FEA products we use, StressCheck® gives me the most confidence when it comes to performing post-processing quality checks on multi-body contact analysis results. StressCheck® has the capability to extract any data of interest and convergence information for that data at any location in the model domain; the other two FEA products do not. And when it comes to interference fit multi-body contact solutions, I haven’t found any software to outperform StressCheck®.”
