NSR&D FY14 Final Report: Friction/Impact Modeling
- Los Alamos National Lab. (LANL), Los Alamos, NM (United States)
The LANL-developed CartaBlanca code uses advanced techniques, including the Dual Domain Material Point (DDMP) method, to calculate fluid, solid motions and fluid-structure interactions. In the last year we have implemented the ViscoSCRAM material model in CartaBlanca based on Clements’ Abaqus-Explicit Finite Element implementation. In this fiscal year, we study numerical properties of this implementation. To consider coupled mechanical, thermal and chemical effects, we have implemented Henson’s HE decomposition model to couple with the thermal and mechanical packages in CartaBlanca. We have also developed porous media flow modules to consider heat convection effects of the reaction product gas inside pores of HE. The next immediate step is to perform numerical simulations to study interactions among these different mechanisms. We have started such calculation and obtained interesting initial results at the end of this fiscal year.
