The adoption of local heat treatments to effectively modify the material behavior is an interesting solution for improving the formability limits of sheet metals during complex forming processes. Being the Finite Element approach the most effective way to design the material modification, in this study we develop a comprehensive constitutive framework to describe the spectrum of plastic responses associated with different levels of annealing, while considering the effect of the anisotropy.

对具有异质特性的金属板材的各向异性演化进行建模


采用局部热处理来有效地改变材料行为是改善复杂成形过程中金属板材的成形性限制的一个有趣的解决方案。有限元方法是设计材料改性的最有效方法，在本研究中，我们开发了一个全面的本构框架来描述与不同退火水平相关的塑性响应谱，同时考虑各向异性的影响。
