Research Institution
A multiscale modeling approach is proposed for the development and implementation of physics-based EOS and constitutive models within a multimaterials continuum modeling framework. Accurate EOS and rate-dependent constitutive (flow, yield stress, damage) models for plate glass, PMMA and segmented elastomers will be developed based upon equilibrium and non-equilibrium molecular dynamics simulations and will be validated through direct comparison of predicted impact behavior with experimental measurements. MD simulations will also facilitate development of improved interfacial models needed for prediction of wave propagation in multilayered materials. The material point method (MPM) will implement these models as well as improved 2- and 3-D crack propagation, fracture, failure and materials interface models, allowing for accurate numerical assessment and optimization of layered structures of various materials and geometries to resist ballistic and blast impact.
