摘要
研究了陶瓷断裂非平衡统计理论.文中从微裂纹随机长大导致断裂的思路出发,给出了随机长大方程,导出了微裂纹分布函数、断裂几率、可靠性、强度和寿命的统计分布函数及其统计平均值。
A nonequilibrium statistical theory of ceramics fracture is studied . The fundamental idea is that microcrack grows stochastically leading to fractures . The equation of stochastic growth is given . The microcrack distribution function , fracture probability , reliability , statistical distribution function of fracture strength and fracture life and their statistical average value are derived .
