LS-DYNA® is optimized for shared and distributed memory Unix, Linux, and Windows based, platforms. Special pricing is available for educational purposes.     LS-DYNA® is a general purpose transient finite element program capable of simulating complex real world problems. Its fully automated contact analysis capability, a wide range of constitutive models and error-checking features have enabled users worldwide to solve successfully many complex problems. LS-DYNA® runs on a large variety of platforms: UNIX Workstations, PCs and Supercomptuers. The code is fully vectorized and in addition to that simulations can be run parallel on multiple processors using either SMP (Shared Memory Processing) or MPP (Massively Parallel Processing).       LS-DYNA® Applications   Automotive Crashworthiness & Occupant Safety:   LS-DYNA® is widely used by the automotive industry to analyze vehicle designs. LS-DYNA® accurately predicts a car's behavior in a collision and the effects of the collision upon the car's occupants. With LS-DYNA®, automotive companies and their suppliers can test car designs without having having to tool or experimentally test a prototype, thus saving time and expense.     Sheet Metal Forming With LS-DYNA®:   One of LS-DYNA®'s most widely used applications is sheet metal forming. LS-DYNA® accurately predicts the stresses and deformations experienced by the metal, and determines if the metal will fail. LS-DYNA® supports adaptive remeshing and will refine the mesh during the analysis, as necessary, to increase accuracy and save time.   Metal forming applications for LS-DYNA® include:   Metal stamping Hydroforming Forging Deep drawing Multi-stage processes   Military and Defense Applications:   LS-DYNA®'s predecessor, LLNL DYNA3D, was originally written for military simulations, and consequently, LS-DYNA® has advanced features for defense applications. LS-DYNA® is capable of simulating projectile penetration, blast response, and explosives.   LS-DYNA®'s military applications include:   Penetration (projectile and armor) Explosives Weapon design Underwater simulations (using USA coupling) Waste containment   Aerospace Industry Applications:     LS-DYNA® is widely used by the aerospace industry to simulate bird strike, jet engine blade containment, and structural failure.   Aerospace applications for LS-DYNA® include: Blade containment Bird strike (windshield, and engine blade) Failure analysis   LS-DYNA®'s potential applications are numerous and can be tailored to many fields. LS-DYNA® is a general-purpose multiphysics simulation software package and is not limited to any particular type of simulation. In a given simulation any of LS-DYNA®'s many features can be combined to model a wide range of physical events. An example of a simulation, which involves a unique combination of features, is the NASA JPL Mars Pathfinder landing simulation which simulated the space probe's use of airbags to aid in its landing. LS-DYNA® is one of the most flexible finite element analysis software packages available.   Other LS-DYNA® applications include: Drop testing Can and shipping container design Electronic component design Glass forming Plastics, mold, and blow forming Biomedical Metal cutting Earthquake engineering Failure analysis Sports equipment (golf clubs, golf balls, baseball bats, helmets) Civil engineering (offshore platforms, pavement design)         LS-DYNA® Analysis Capabilities Nonlinear dynamics Rigid body dynamics Quasi-static simulations Normal modes Linear statics Thermal analysis Fluid analysis Eulerian capabilities ALE (Arbitrary Lagrangian-Eulerian) Fluid-structure interactions FEM-rigid multi-body dynamics coupling (MADYMO, CAL3D) Underwater shock Failure analysis Crack propagation Real-time acoustics Design optimization Implicit springback Multi-physics coupling Structural-thermal coupling Adaptive remeshing Smooth particle hydrodynamics element-free meshless method LS-DYNA®'s comprehensive library of material models: Metals Plastics Glass Foams Fabrics Elastomers Honeycombs Composites Concrete & soils High explosives Propellants Viscous fluids User-defined materials LS-DYNA®'s large element library: Solids 8-node thick shells 4-node shells Beams Welds Discrete zero length beams Trusses and cables Nodal masses Lumped inertias LS-DYNA®'s contact algorithms: Flexible body contact Flexible body to rigid body contact Rigid body to rigid body contact Edge-to-edge contact Eroding contact Tied surfaces CAD surfaces Rigid walls Draw beads LS-DYNA®'s specialized automotive features: Seatbelts Sliprings Pretensioners Retractors Sensors Accelerometers Airbags Hybrid III dummy models Inflator models   BACK TO TOP          \\ home \ products \ lstc \ ls−dyna      © PhilonNet All Rights Reserved   DISCLAIMER     SITE     CONTACT
