相场方法允许方便和有效的移动界面模拟。本文提出了不同阶次的相场方法，并应用于模拟温度相关的非线性弹性材料的固体损伤。数值框架提供了一种基于NURBS的有限元方法，它最大限度地减少了数值和计算工作量，而不会损害问题所需的平滑度。
Phase field methods allow for convenient and efficient moving interface simulations. In this paper phase field approaches of different order are presented, and applied to simulate damage in solids of temperature dependent and non‐linear elastic materials. The numerical framework provides a NURBS based finite element method which minimizes the numerical and computational effort without impairing the smoothness required by the problem.
