摘要
利用Katayama在一种Si_3N_4陶瓷得到的实验数据,考察了一条关联陶瓷材料三点及四点弯曲断裂强度的式子。其准确度较好。简要地导出了一般教材上较少提及其推导的四点弯曲加载因子。
This paper verifies an expression, which is rarely mentioned in textbooks, relating the results of 3-point and 4-point bending tests of ceramic materials on fracture strength with the experimental data obtained by Katayama. The expression is shown to be of satisfactory accuracy. The load factor for 4-point bending test, whose derivation is usually not included in textbooks, is also derived in this paper.
