Latest Patents

Lawrence Chai holds a patent for a "Material point method for simulation of granular materials." This innovative approach provides a method for simulating and rendering granular materials effectively. The simulation application generates video frames that depict granular material phenomena using a strain-based elasto-plastic constitutive model integrated with a hybrid Eulerian/Lagrangian material point method (MPM). The elasto-plastic constitutive model includes physical equations that dictate the forces affecting the granular material during the simulation. Notably, the model allows for user-controllable parameters that define thresholds for initiating plastic deformation, as well as a hardening parameter that controls the rate at which the granular material packs under compression. The MPM procedure couples particles of the granular material with a background grid, which assists in computing forces dictated by the physical equations of the elasto-plastic constitutive model. In one configuration, the grid can be rendered with volumetric rendering to generate video frames that depict the granular material.
