9313233莫兰这项研究将发展用于固态相变定量分析的非线性(材料和几何)和非局部有限元方法。基于Landau-Ginzburg自由能最小化的有限元统一方法将被发展应用于三维形核。所开发的方法将提供界面能的定量预测，并使人们更深入地理解非线性和非定域性对涉及晶体结构变化的固相反应的影响。***

9313233 Moran This research will develop nonlinear (both material and geometric) and nonlocal finite element methods for the quantitative analysis of solid-state phase transformations. A unified approach based on minimization, via finite elements, of the Landau-Ginzburg free energy will be developed for application to three-dimensional nucleation. The methods developed will provide quantitative predictions of interfacial energies and lead to a deeper understanding of the effects of nonlinearity and nolocality on solid-state reactions involving change in crystal structure. ***
