摘要 本文用细观损伤力学的方法对理想的无裂纹陶瓷试样最大拉伸断裂应力的尺寸效应进行了分析 ,解释了材料的最大拉伸载荷随试件宽度的减小而增大的原因。理论分析结果与对Al2 O3 Based on damage mechanics,this article analyzes the size effect of the maximum tensile strength of uncracked ceramic specimens,and points out the reasons of the increment of tensile stress with the height decreasing.An experimental validation is given through three point bending method.
