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)

LS-DYNA is a product of Livermore Software Technology Corp. (LSTC)

LS-DYNA for Automotive Crash

LS-DYNA provides highly scalable solutions to transient problems.

LS-DYNA for Occupant

CASE STUDY

Numerical simulation of protection systems on agricultural tractors to ensure standards compliancy

Virtual testing of roll-over protection and of falling-object protection in the early design phase ensures safety performance

This technical case study describes how the ROPS and FOPS of a tractor were numerically studied in the early design phase to ensure compliance with OECD Standard Code 4 (for the cabin’s resistance to longitudinal, lateral and vertical energy or force) and Code 10 (for overhead protection from falling objects).
