6005铝合金激光-MIG复合焊后超声冲击处理及其力学性能
激光-MIG复合焊接是一种新型高效铝合金焊接方法.与传统熔化焊相似，激光-MIG复合焊接接头也存在残余应力问题，影响了接头力学性能及安全可靠性.本文采用超声冲击的方法对6005铝合金激光-MIG复合焊接接头进行焊后处理，并研究了超声冲击处理后接头的静态拉伸性能和疲劳性能，并采用X射线法测试了残余应力分布变化，结果表明由于超声冲击作用该善了铝合金焊接接头的残余应力分布，降低了应力峰值，焊接接头的疲劳

基于稳态耗散能的高周疲劳损伤模型及剩余寿命预测
材料疲劳过程中的能量耗散在宏观上表现为热耗散，而与疲劳损伤相关的耗散能是表征材料微结构演化的重要参量。基于一种疲劳载荷下的单循环耗散能计算方法，计算出相对准确的单循环耗散能。以316L不锈钢材料为研究对象，通过系列高周疲劳实验，实时监测高周疲劳破坏全过程中单循环耗散能变化规律，拟合出稳态能量耗散阶段单循环耗散能-疲劳寿命曲线。
