The effect of pre-strain on fatigue for a high strength low alloy (HSLA) steel

[摘要] The effect of initial plastic strain cycle fatigue lives of HSLA specimens is investigated. Specimens were monotonically, quasi-statically loaded under strain control in tension to produce plastic strains (prestrain conditions s 0 = 0, s...
