Previous ISN efforts have furnished unique capabilities to model material fracture and failure with unprecedented fidelity. Building on these results, the goal of this project is to develop and validate a scalable simulation capability to analyze fracture of novel protective material systems under development at the ISN as well as to complement Army Research Laboratory (ARL) efforts. The approach will be to exploit and extend legacy simulation capabilities with special focus on coupling atomistic models of dicyclopentadiene polymer networks (DCPD) developed by ARL with continuum level discontinuous Galerkin/Cohesive Zone and Peridynamics capability. Particular interest was elicited in jointly developing a monolithic multiscale Peridynamics capability building on existing approaches developed at ARL and MIT. A critical aspect of the project will be the experimental validation using experimental data provided by ARL collaborators as well as by novel micron-scale laser-driven shock experiments to be conducted by ISN on new soft-hard hybrid composites to be synthesized at the ISN.
The main objective of this project is to develop and validate a multi-scale scalable simulation capability for the large-scale simulation and analysis of fracture of novel protective material systems under development at the ISN as well as to complement material modeling efforts within the ARL-WMRD Materials Campaign.
