韧性金属的一个重要失效机制是 微观空隙的生长和合并。 在这项工作中,将开发一个显式欧拉代码, 在微观力学水平上研究固体的动态破坏 通过空隙的增长和聚合。 高度复杂的, 超高速精确界面跟踪方法 将采用撞击和穿透计算, 新的表面 欧拉计算的准确性将 从而更深入地了解这一重要的故障机制。
英文摘要
An important failure mechanism for ductile metals is the growth and coalescence of microscopic voids. In this work an explicit Eulerian code will be developed to study at the micromechanical level the dynamic failure of solids by void growth and coalescence. The highly sophisticated and accurate interface tracking methods developed for hypervelocity impact and penetration calculations will be adopted for evolving new surfaces. The accuracy of the Eulerian calculations will result in greater insight into this important failure mechanism.
