Enhanced Adaptive Phase-Field Modeling of Brittle Fracture in Heterogeneous Materials: Integration of PHT-Splines

This study introduces a sophisticated adaptive phase-field model de-signed to simulate brittle fracture in heterogeneous materials. By incorporating PHT-splines, the model significantly improves the accuracy of crack propagation predictions. It effectively captures crack initiation and growth in materials with intricate microstructures, particularly enhancing precision in areas with sharp property variations. Through numerical simulations of brittle fracture in materials like ceramics, the model demonstrates its capability to accurately predict crack paths and energy dissipation during fracture. The research presents an innovative approach by integrating adaptive phase-field techniques and PHT-splines, offering a powerful tool for more precise fracture simulations in engineering contexts.
