MEPLS is an open-source object-oriented framework for simulating the plastic deformation of materials based on the combination of stochastic processes and solid mechanics. I’ve developed it over my years of research in the statistical modeling of materials, although it’s still a work in progress. Its goal is to provide modular, efficient, and easy-to-use tools to build simulations for a broad range of physical scenarios. MEPLS abstracts away unnecessary complexity, allowing the user to focus on the physics of the model.
