[SY-G3] Simulations on severely transient FSI problems associated with shock compression of matters in extreme conditions
Invited
Some special numerical techniques are desired when simulating the behavior of matters in extreme conditions, and in particular, the chemical-thermal energy release from the combustion of explosives and propellants must be carefully addressed when capturing the high strain rate deformation of metals and polymeric binders interacting with the energetic elements of the system. In this talk, selective research accomplishments associated with modeling of both energetic and inert matters exposed to high pressure conditions are discussed. Models are developed for addressing the problems of shock-induced ignition and multi-scale hot spot initiation of metalized energetic components from the shock compression system.
To do so, one needs to adapt a stable interface tracking algorithm for severely transient fluid-structure interaction problems. We have developed a multi-material hydrodynamic shock physics code with a hybrid particle level set method for simulating the shock induced chemical reaction of energetic materials and volumetric deformation of metals. The experimental measurements are obtained to validate the simulated results presented in this talk.
