Abstract Review of selected fundamental topics on the interaction between phase transformations, fracture, and other structural changes in inelastic materials is presented. It mostly focuses on the concepts developed in the author’s group over last three decades and numerous papers that affected us. It includes a general thermodynamic and kinetic theories with sharp interfaces and within phase field approach. Numerous analytical (even at large strains) and numerical solutions illustrate the main features of the developed theories and their application to the real phenomena. Coherent, semicoherent, and noncoherent interfaces, as well as interfaces with decohesion and with intermediate liquid (disordered) phase are discussed. Importance of the surface- and scale-induced phenomena on interaction between phase transformation with fracture and dislocations as well as inheritance of dislocations and plastic strains is demonstrated. Some nontrivial phenomena are discussed and modeled.

非弹性材料的相变、断裂和其他结构变化

摘要 介绍了非弹性材料中相变、断裂和其他结构变化之间相互作用的选定基础主题。它主要关注作者团队在过去三年中开发的概念以及影响我们的众多论文。它包括具有清晰界面和内相场方法的一般热力学和动力学理论。许多分析(即使在大应变下)和数值解说明了已发展理论的主要特征及其在实际现象中的应用。讨论了相干、半相干和非相干界面,以及具有分离和中间液相(无序)相的界面。证明了表面和尺度诱导现象对相变与断裂和位错之间的相互作用以及位错和塑性应变的继承的重要性。一些非平凡的现象被讨论和建模。
