Mechanical modelling of the deformation and failure behaviour of particulate-reinforced composites of ZrO2-ceramics and TRIP-steel (C05)

C5项目的目的有两个：第一，模拟断裂过程区的细观损伤机制。其次，模拟了循环载荷作用下颗粒增强TRIP基复合材料的相变、变形和损伤行为。为了加深对复合材料在循环加载过程中变形和损伤过程之间相互作用的理解，将进行细观模拟。本文的本构模型将被修正以捕捉循环响应，并通过非局部损伤公式和热力耦合对其进行扩展。

The aims of project C5 are twofold: Firstly, to simulate micromechanical damage mechanisms in the fracture process zone. Secondly, to model phase transformation, deformation and damage behavior of particle reinforced TRIP-matrix-composites for cyclic loading. To foster the understanding of the interplay between deformation and damage processes in the composite during cyclic loading, micromechanical simulations will be carried out. The present constitutive model will be modified to capture cyclic response and extended by a nonlocal damage formulation and thermomechanical coupling.
