【摘要】 在D36钢焊接对接接头的低周疲劳试验的基础上,利用Manson-Coffin定律对试验数据进行了分析处理,得出了焊接接头应变与疲劳寿命之间的关系,利用这一关系可以对任意应变下焊接接头的疲劳寿命进行预测.同时,对焊接接头疲劳寿命的影响因素进行了讨论.更多还原

【Abstract】 On the basis of low cycle fatigue experiment of D36 steel, the relatioaship between fatigue life and strain of weld joint is obtained as data processing according to Manson-Coffin law. The fatigue life of weld joint then is predicated by the use of relationship obtained. The factors affected the fatigue life are discussed, too.更多还原
