The long term goal of part project A7 is the development of a systematic scale bridging approach for modeling the micro mechanics of multi-phase materials using ab initio data. To achieve this a constitutive model for TWIP/TRIP materials has been developed based on the underlying physical phenomena. The focus of the third period of the proposal will be to include the effect of hydrogen on the plastic behavior as well as studying in detail the interaction between the different phases of multi-phase materials.

部分项目A7的长期目标是开发一种系统的规模桥接方法，用于使用从头算数据模拟多相材料的微观力学。为了实现这一目标，已经开发了一个本构模型的基础上的基本物理现象的TTRIP/TRIP材料。该提案第三阶段的重点将包括氢对塑性行为的影响，以及详细研究多相材料不同相之间的相互作用。
