Subproject C03 deals with the development and application of combined test methods for the determination of fracture and damage mechanical properties of novel ceramic materials at test temperatures of up to 1600 °C. Experimental setups based on the Small Punch Test, miniaturized 4-point bending test with Chevron-notched specimens, and the Brazilian Disc test are to be geometrically adjusted in such a way that stably growing cracks and damage-mechanical process zones can be analyzed during the tests. Local strain and stress fields as well as stress intensity factors are then to be determined with the help of optical field measurements and the finite element method.

子项目 C03 涉及组合测试方法的开发和应用，用于测定新型陶瓷材料在高达 1600 °C 的测试温度下的断裂和损伤机械性能。基于小冲头试验、带有 V 形缺口样本的小型化 4 点弯曲试验和巴西圆盘试验的实验装置应进行几何调整，以便在试验过程中分析稳定增长的裂纹和损伤机械过程区域。然后借助光场测量和有限元方法确定局部应变和应力场以及应力强度因子。
