Determination of temperature-dependent fracture and damage mechanical properties of ceramic filter materials from small scale specimen (C03)

分项目C03涉及在高达1600 °C的试验温度下测定新型陶瓷材料断裂和损伤力学性能的综合试验方法的开发和应用。基于小冲杆试验、带V形缺口试样的小型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，以便在试验期间分析稳定增长的裂纹和损伤机械过程区。局部应变和应力场以及应力强度因子，然后确定与光场测量和有限元法的帮助下。

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.
