Numerical Simulation of Explosive Welding using LS-DYNA ALE Multi-material Approach

Popis výsledku v původním jazyce

Explosive welding or bonding is a useful technical procedure producing, for example, protective barriers, bi-metallic plates and tubes or for bonding tubes into a collector steam-generator plates. In the past, it was successfully studied and establishedby using mainly empirical experience. Currently, very powerful numerical tools (3D dynamic finite element or finite difference codes) are available that enable to study most involved aspects of explosive welding theoretically. The paper presents numerical 3D simulations of nickel-steel and titanium-steel explosive welding. The explosive used, Semtex 30, was described by JWL state equation, the metallic plates were described by the Johnson-Cook constitutive model, and the air was described by the ideal gas equation of state. For numerical solution, the ALE multi-material method implemented in the LS-DYNA code was used. The basic aspects of the explosive welding obtained through the numerical simulations are presented and discussed.
