Hierarchical Multiscale Framework for Materials Modeling: Equation of State Implementation and Application to a Taylor Anvil Impact Test of RDX.

Popis výsledku v původním jazyce

In order to progress towards a materials-by-design capability, we present work on a challenge in continuum-scale modeling: the direct incorporation of complex physical processes in the constitutive evaluation. In this work, we use an adaptive scale-bridging computational framework executing in parallel in a heterogeneous computational environment to couple a fine-scale, particle-based model computing the equation of state (EOS) to the constitutive response in a finite-element multi-physics simulation. The EOS is obtained from high fidelity materials simulations performed via dissipative particle dynamics (DPD) methods. This scale-bridging framework is progress towards an innovation infrastructure that will be of great utility for systems in which essential aspects of material response are too complex to capture by closed form material models. The design, implementation, and performance of the scale-bridging framework are discussed. Also presented is a proof-of-concept Taylor anvil impact test of non-reacting 1,3,5-trinitrohexahydro-s-triazine (RDX).
