Peking University(@PKU1898):New Graph-Field(GF) Framework predicts fracture in lattice materials. A team led by Prof. Wei Xiaoding at the Peking University School of Mechanics and Engineering Science, in collaboration with Beijing University of Technology, has developed a Graph-Field (GF) framework to predict crack propagation in architected lattice materials. The method derives continuum equations directly from lattice topology, eliminating empirical parameters. It accurately captures crack-tip deformation and crack paths that classical homogenization models miss, providing a rigorous foundation for designing damage-tolerant lightweight structures.
