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
