Abstract: This study discusses a new constitutive model called the High Rate-Brittle (HRB) Microplane model and also presents the details of a new software package called the Virtual Materials Laboratory (VML). The VML software package was developed to address the challenges of fitting complex material models such as the HRB Micro plane model to material property test data and to shtdy the behavior of those models under a wide variety of stress- and strain-paths. The VML code is used to fit the new HRB Micro plane model to a well-characterized conventional strength concrete called WES-5000. The ability of the HRB Microplane model to provide high-fidelity simulations of material property experiments was also demonstrated. Finally, the behavior of the HRB Microplane model was examined with respect to penetration applications of interest. It was shown that, when adequately fit to the quasi-static material data, the HRB Microplane model did not have significant predictive capabilities. This was attributed to the rate-dependent response of the material. After various rate effects were introduced into the HRB Microplane model, the quantitative predictive nature of the calculations dramatically increased.
