塑性金属的一个重要破坏机制是微观孔洞的生长和聚并。在这项工作中，一个明确的欧拉代码将被开发，以研究在微观力学水平的动态破坏的固体的空隙生长和合并。为超高速碰撞和侵彻计算而开发的高度复杂和精确的界面跟踪方法将用于不断发展的新表面。欧拉计算的准确性将使我们更深入地了解这一重要的失效机制。
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.
