COMSOL models for a coupled phase-field framework of dissolution-to-fracture transition

This dataset contains the COMSOL Multiphysics model files developed for a coupled phase-field framework describing the transition from localized corrosion to hydrogen-assisted fracture. The models incorporate electrochemical dissolution, metal-species transport, mechano-electrochemical coupling, FRDR-controlled passive-film kinetics, stress-assisted hydrogen transport, and phase-field fracture. The files are provided to support reproduction and further development of the numerical framework presented in the associated manuscript.本数据集包含为耦合相场（phase-field）框架开发的COMSOL Multiphysics（科姆索尔多物理场）模型文件，该框架用于刻画局部腐蚀向氢辅助断裂的转变过程。该系列模型集成了电化学溶解、金属物质输运、力电耦合、FRDR调控的钝化膜动力学、应力辅助氢输运及相场断裂等关键物理与数值模块。提供本数据集的目的在于支持关联学术手稿中提出的数值框架的复现与进一步开发。
