Phase-field modeling of thermal shock-induced fracture in layered materials

Such thermally induced fracture behaviors are governed by multi-physical field coupling effects among material properties, geometric configurations, and thermal boundary conditions. However, the sensitivity mechanisms of these key parameters have not been systematically quantified, leading to a lack of universal theoretical support for crack-resistant design.To address this challenge, this study establishes a unified thermo-mechanical phase-field model, enabling multi-parameter coupled analysis of thermally induced crack nucleation and growth in layered systems.

The model quantitatively reveals how geometric dimensions and material property ratios control cracking mechanisms, providing predictive capabilities for coating performance and structural optimization in industrial applications. The highlights of the article are summarized as follows:1. Developed a robust thermo-mechanical phase-field model for layered material fracture analysis, demonstrating high adaptability and predictive accuracy.2.
