摘要
根据16Mn钢对接焊接接头的疲劳试验数据,对Miner线性累积损伤准则进行了修正,提出了一定可靠度下疲劳累积损伤的计算方法,为估算16Mn钢焊接构件在谱载荷作用下一定可靠度的疲劳寿命提供了依据.
Based on constant amplitude fatigue life of 16 Mn steel with welded joint, this article modified Miner′s formula and proposed a new method for estimating the accumulative damage and provides the foundation for estimating the fatigue life of 16 Mn steel with welded joint under a given confidence.
