Multiple cracks interaction model under creep conditions

摘要：

　　Multiple flaws are often found in many high-temperature structural components.The interaction and coalescence of multiple cracks may significantly influence the service lives of these high-temperature components.In this paper,the interaction effect on multiple cracks is investigated under creep conditions.At the same time,interaction is considered during crack growth calculation by including the appropriate magnification factors in the calculations of creep fracture parameters.Based on these analyses,the assessment method of high-temperature structure containing multiple flaws is developed.
