LS-DYNA´S CONTACT ALGORITHMS
|
Constraint and penalty techniques have worked extremely well over the past 20 years in numerous applications. Coupled thermomechanical contact can also be handled. Over 25 different contact options are available. These options primarily treat contact of deformable to deformable bodies, single surface contact in deformable bodies and deformable or rigid to rigid body contact. Multiple definitions of contact surfaces are possible as outlined below. All contact definitions are AUTOMATIC.
- Single surface contact
- Contact with rigid walls
- Edge-edge contact
- Beam-beam contact
- Eroding contact
- Contact with CAD surfaces
- Tied surfaces
- 2D-contact
- Shell edges tied to shell surfaces
- Resultant force contact
- Fluid-structure interfaces
- Pinball contact
Friction models:
- Static and dynamic coulomb
- Viscous friction
- Pressure dependent friction
- User-defined friction models
