Latest Patents

Songsong Bai holds a patent for a groundbreaking invention titled "Discrete Element Method (DEM) Contact Model Building Method for Reflecting Weakening of Seepage on Rock and Soil Mass Strength." This patent outlines a sophisticated discrete element method contact model which includes several critical steps. The process begins with selecting a filling body in a disaster-causing structure to analyze the cumulative loss patterns of the filling body. Through extensive test simulations, the model establishes a relation function for various mesoscopic mechanical parameters over time. This function is then integrated into an existing particle contact model. Additionally, the invention details how to update the fracture failure criteria based on the macro-mesoscopic strength relationships during model failures. The final phase involves creating a seepage failure discrete element calculation model, which simulates the seepage failure process using the refined particle contact model and fracture criterion.
