LS-DYNA
LS-DYNA® from Livermore Software Technology Corp. (LTSC) is the world's most advanced general-purpose nonlinear finite element program. It is capable of simulating complex real-world problems, and is widely accepted as the premier analysis software package for today's most challenging engineering applications.
LS-DYNA can predict how a prototype will respond to real-world events such as crashes, drops, earthquakes, bird strikes, and so on. The ability to simulate these events in software minimizes the time and expense that must be devoted to experimental testing.
LS-DYNA is well optimized on all platforms including multi-processor platforms (see table below). Its accuracy has been proven through extensive correlation with experimental data and, of course, analytical solutions. LS-DYNA is an invaluable tool for capturing extreme nonlinear events where other solvers have failed.
Benefits:
- Simulate complex crash and deformation engineering problems
- Combine complementary simulation disciplines such as crash, structural analysis, occupant safety, NVH and others
- Have confidence that your virtual models have a high degree of correlation to physical testing prototypes
- Increase confidence in your final product design by virtually testing it under all conceivable loading conditions
- Ensure customer satisfaction by providing long-lasting products that have survived the most extreme conditions imaginable
Applications:
- Automotive crashworthiness and occupant safety
- Projectile penetration, blast response, and explosives
- Metal forming, forging, stamping, and deep drawing
- Bird-strike scenarios and jet engine blade containment
- Transport-container design and drop testing
- Plastics, mold, and blow forming
- Civil engineering, earthquake analysis
- Failure analysis
