Description
Summary:The dual domain material point (DDMP) method, an extension of the material point method, is applied to investigate compaction and crushing of sugar pearls and rock sugar crystals undergoing large deformation and failure. DDMP is chosen because of its capability to simulate complex geometry and to avoid mesh tangling that is often encountered in finite element methods. Numerical results of the compaction and breakup of individual sugar pearls, multiple of sugar pearls, and multiple rock sugar crystals are compared with experimental results. The compaction of multiple rock sugar crystals introduces a pre-processing challenge due to the complex initial geometry. To address this challenge, a fast method is introduced to generate initial material point locations given a stereolithography (STL) file. The method is scalable to generate billions of material points using a single processor in a feasible time frame.
