Multi-body Contact

Included in StressCheck Core is the functionality to set up multi-body contact analyses quickly and easily.  Simply declare the contact regions for each part to be analyzed, connect the regions via contact constraints, and solve elastic or elastic-plastic materials.  No gimmicks, no special elements required.  There can be one contact pair or many, as there is no limit to the number of parts in the analysis.

  • The meshes on the mating surfaces do not need to match

  • The formulation, based on the augmented Lagrangian algorithm, delivers high efficiency

  • Elastic-plastic solutions are supported using a dual-iteration procedure

  • Neat fit, interference fit and clearance conditions can be specified
