LS-DYNA is an advanced general-purpose multiphysics simulation software package that is developed by the Livermore Software Technology Corporation (LSTC). While the package continues to contain more and more possibilities for the calculation of many complex, real world problems, its origins and core-competency lie in highly nonlinear transient dynamic finite element analysis using explicit time integration. LS-DYNA is used world-wide by Automobile, Aerospace, Military, Manufacturing, and Bioengineering companies.
Typical uses include:
- Changing boundary conditions (such as contact between parts that changes over time)
- Large deformations (for example the crumpling of sheet metal parts)
- Nonlinear materials that do not exhibit ideally elastic behavior (for example thermoplastic polymers)
- Transient dynamics of short duration events where inertial forces are important
- Automotive crash (deformation of chassis, airbag inflation, seatbelt tensioning, occupant safety)
- Explosions (underwater mines, shaped charges)
- Manufacturing (sheet metal stamping, forging, tube bending)
