Ansys LS-DYNA

One of the most flexible finite element analysis software packages

LS-DYNA is a general-purpose finite element program capable of simulating complex real world problems. It is used by the automobile, aerospace, construction, military, manufacturing, and bioengineering industries. LS-DYNA is optimized for shared and distributed memory Unix, Linux, and Windows based, platforms, and it is fully QA'd by LSTC. The code's origins lie in highly nonlinear, transient dynamic finite element analysis using explicit time integration.

"Nonlinear" means at least one (and sometimes all) of the following complications:

  • 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 dynamic" means analyzing high speed, short duration events where inertial forces are important. Typical uses include:

  • Automotive crash (deformation of chassis, airbag inflation, seatbelt tensioning)
  • Explosions (underwater Naval mine, shaped charges)
  • Manufacturing (sheet metal stamping)

Main Benefits:

  • Any of LS-DYNA's many features can be combined to model a wide range of physical events
  • ull 2D & 3D capabilities
  • Nonlinear dynamics
  • Rigid body dynamics
  • Crack propagation
  • Real-time acoustics
  • Implicit springback
  • Multi-physics and Structural-thermal coupling
  • and many others
