本文提出了一种新的计算框架，用于描述金属添加剂制造过程中颗粒组织的演变，并模拟添加材料的非弹性变形，显式地考虑了颗粒结构。研究了颗粒结构和加载条件对附加加工试件应力-应变状态演化的综合影响。研究结果强调了考虑实际微观结构的需要，以适当地描述添加制造的试件和部件的机械行为。这是关于小规模力学-EUROMAT的专题问题的一部分。
This paper presents a new computational framework to describe the evolution of grain structure during metal additive manufacturing and to simulate an inelastic deformation of the additively manufactured material, taking into account the grain structure explicitly. A combined effect of grain structure and loading conditions on the evolution of the stress–strain state in additively manufactured specimens is investigated. The results of the research highlight the need to account for the realistic microstructure, to properly describe the mechanical behaviour of additively manufactured specimens and parts. This is part of a thematic issue on Small Scale Mechanics - EUROMAT.
