摘要
本文研究了原子键机理与宏观特性相结合的热激活断裂非平衡统计理论,统一导出了微裂纹分布函数、断裂几率、可靠性、断裂寿命分布函数和平均断裂寿命。
A nonequilibrium statistical theory of thermally activated fracture connecting atomic bond mechanism with the microscopic properties has been constructed The stochastic growth equation of microcrack is given. The microcrack distribution function, fracture probability, reliability, fracture life distribution function and average fracture life have been derived in a unified theory.
