PERMAS offers the following modules for static Analysis:
- PERMAS-LS - Linear Statics
- This module allows for linear elastic calculations based upon the assumptions of small displacements, small strains, and linear material behaviour.
- PERMAS-CA - Contact analysis
- Static analyses under nonlinear contact constraints
- PERMAS CAX - Extended Contact Analysis
- New contact solution algorithms for large friction contact models.
- PERMAS CAU - Contact Geometry Update
- Contact with large relative motions between contact partners.
- PERMAS CAMG - Contact multigrid solver
- New contact solver generation for very large contact models.
- PERMAS WLDS - Weldspot Model
- Good representation of the global stiffness for spot welded structures.
- PERMAS NLS - Nonlinear Statics
- Nonlinear analysis of models with large displacements and/or nonlinear material behavior.
- PERMAS NLSMAT - Extended Material Laws
- Material laws for cast-iron and nonlinear material hardening under cyclic loads.
- PERMAS NLSA - Hyperelastic Material
- Large strain analysis.
- PERMAS BA - Linear Buckling
- A linear buckling model to determine load factors and mode shapes.
- PERMAS LA - Laminate Analysis
- Modeling and analysis of multi-layered fibre-reinforced composites.
