Effect of inclusions on temperature and loading rate dependent strength, deformation and failure behavior (C05)

该项目的重点是详细研究非金属夹杂物开始裂纹扩展的动力学作为温度和加载速率的函数。通过现场声发射分析，分别评价了韧性断裂和解理断裂的损伤效果。研究了非金属夹杂物的空间分布、尺寸分布和形状分布对裂纹扩展起始动力学和裂纹扩展稳定性和不稳定性的影响。

The project is focused on the detailed investigation of the kinetics of the onset of crack growth at non-metallic inclusions as a function of temperature und loading rate. The damaging effect of ductile fracture and cleavage fracture is evaluated separately by analyzing acoustic emissions in-situ. The effect of the spatial distribution and the distribution of size and shape of the non-metallic inclusions on the kinetics of the onset of crack growth and the stable and/or unstable crack propagation is investigated as a function of the crack opening mode.
