Abstract
The effect of prestrain on fatigue behavior in various kinds of materials has been reported on several times thus far Ref 111 That being said however the number of actual systematic research works on this topic is quite few and it is still unclear whether prestraining is of any benefit in fatigue properties presumably depending on the material and its microstructure Furthermore in particular the effect of compressive prestrain on pulsative tensile fatigue behavior has not been reported on in correlation with cyclic plastic strain response for the materials strengthened by different mechanisms which is very important in engineering application However it has so far been considered that the measurement of cyclic plastic strain response under the condition of tensile fatigue is extremely difficult because of its smallness In the present study the influence of compressive prestrain on fatigue properties in two types of aluminum alloys 5056H34 Al alloy and 6061T6
