in the rupture region was inversely proportional to yield strength. Key words: Al–Zn–Mg–Sc–Zr alloy; annealing treatment; microstructures; fatigue crack growth rate; fatigue crack path Cite this article... crack propagation behavior. In general, the fatigue crack propagation rate is intimately bonded to yield strength of materials. The crack tip plastic blunting model put forward by LAIRD et al [36......
The Warm Deformation Treatments for Improving the Resistance of High Strength Steel Wires to Low Cycle Fatigue and Room Temperature Creep () [全文内容正在添加中] ......
of static strength for the composite material laminates with a circular hole, the stress correct factorβ is presented. In order to gain the factorβ, the fatigue experiments of laminates with holes in different diameters and the same ratio of width and diameter. The fatigue behavior is usually accompanied with extensive damages. Those damages can affect composite materials in their strength......
