  • Publication number: 20250045488
    Abstract: The present invention belongs to the field of computational mechanics, and provides an adaptive multi-level phase-field method for brittle fracture of elastic materials under thermal shock, thus to provide a new numerical calculation method for efficient fracture study. In the present invention, damage degree of a material is characterized by a phase field, and the multi-level hp-FEM is used as an adaptive strategy to implement dynamic discretization in a process of crack propagation under thermal shock. Compared with previous adaptive phase-field fracture models, the present invention has no hanging nodes, and has simple numerical implementation and high calculation efficiency, which can effectively predict the fracture behavior of a structure. At the same time, three pre-existing crack treatment techniques are developed to initialize the phase field.
