Aims of project B4 are the characterization of structure-property correlations, the extension of concepts on structure assessment and residual fatigue lifetime and the validation of simulation models of project C5. The biaxial material behavior regarding deformation, phase transformation, damage and crack growth of powder metallurgical TRIP steels and TRIP-matrix composites as well as welded structures will be studied. Investigations on cyclic crack growth, fatigue, cyclic creep and quasi-static deformation using a biaxial-planar testing system as well as quasi-hydrostatic high-pressure tests are planned.

项目B4的目标是表征结构-性能相关性，扩展结构评估和剩余疲劳寿命的概念，并验证项目C5的模拟模型。研究了粉末冶金TRIP钢、TRIP基复合材料以及焊接结构的变形、相变、损伤和裂纹扩展等双轴材料行为。计划使用双轴平面试验系统以及准静水高压试验对循环裂纹扩展、疲劳、循环蠕变和准静态变形进行调查。
