Seamless Comparative Modeling of Natural Hazards Using the Material Point Method

A theoretical framework is developed for applying the material point method (MPM) to problems of modeling natural hazard effects on several representative geometries. Following an outline of the general methodology, in which the structural system is replaced by a combination of integrated Lagrangian point masses that can move through Eulerian space, examples are shown for (1) the large deformation behavior of beam-like structures, (2) the impact between two particles, and (3) the failure of a granular slope. Key aspects of this work and approach include the ability to model large deformations, the ease of incorporating nonlinear constitutive relations, the ability to model everything from either continuous solids to granular media, and an approach to model multiple materials in the same analysis. Eventually, these computational tools can be combined with imaging methods to track the analysis of the original physical system mapped to an MPM domain using point cloud, rather than continuous, photographic imaging.
