In recent years industries like aerospace, automotive and those related to oil production have increased their trustfulness on numerical models and codes for the design, research, production and verification of highly critical parts ...

Hot stamping is one way to produce automotive steel parts of a complex shape with very high mechanical characteristics. In this process heat plays an essential role. To reduced investment costs and for more production flexibility ...

An electromagnetism module has being developed in LS-DYNA for coupled mechanical/thermal/electromagnetic simulations. More recently, a new 2D axi-symmetric version of this solver was introduced, allowing much faster simulations. In ...

Impact welding enables metallurgical bonding even between dissimilar metals. The bond is formed during a high speed impact between the two workpieces to be joined. In the application, the accelerating force is provided by an explosive ...

A novel carbon fiber reinforced metal laminate based on thermoplastic polymer is investigated in the project LEIKA. For the safeguarding of the production of the parts made of this material, coupled thermo-mechanical simulations have ...

LS-DYNA’s origins and core-competency lie in its well-known contact Algorithms, which is very powerful and functional. In order to simulate the details in the contact zones of bolt connection of the magnesium stabilizer clamp under ...

Airbags are part of an important vehicle safety system, and the inflator is an essential part that generates a specific volume of gas to the airbag for a short duration of time. Recently, we have developed numerical models of ...

A new feature of random vibration analysis is available in LS-DYNA since version 971, which has been shown to be a powerful tool for the simulation of vibration shaker table test driven by power spectrum density (PSD). In particular, ...

In deep-drawing dies for steel sheet parts of car bodies huge masses are moved. To prevent vibrations, which occur by sudden acceleration or stopping of those masses, elastomeric tubular dampers [1] are used. The dampers are made out ...

Topology optimization considering transient nonlinear behavior of mechanical structures, e.g. automotive crash, remains a challenge in both the implementation as well as computational effort. In recent years, efficient optimization ...
