|Abstract:||Microcrack interaction and its effect on slow crack-growth in brittle solids are studied numerically, assuming a uniform distribution of microcracks around the main crack. The results show that microcracking produces a profound influence on the growth rate of the main crack in the material. When microcracking is extensive in the material, the crack growth-rate is generally retarded, but when microcracking is not as extensive, the crack growth rate fluctuates, being enhanced in some instances and retarded in others. The results are discussed in relation to the life of ceramic tool-tips under different machining conditions. © 1990.|
