Variation of tensile and bending rigidities of a duplex embossed steel sheet by small uniaxial tensile deformation

Comparison of low cycle fatigue behavior of 304 stainless steels induced by tensile and torsional prestrain

“…Many scholars studied the effect of tensile prestrain on uniaxial tensile properties and concluded that the yield strength increased whereas elongation decreased after tensile prestrain. [2][3][4][5] Uniaxial tensile responses of 304 stainless steel after torsional prestrain and tensile prestrain are shown in Figure 2. The data after torsional prestrain were reproduced from our previously published articles.…”

“…It was found that with the increase of tensile prestrain, the yield and tensile strength increased whereas the ductility and low cycle fatigue (LCF) life decreased. [2][3][4][5][6] In addition, a large prestrain in the plastic deformation stage, for example, necking stage, will cause great damage to materials. 7 During the prestrain process, dislocation walls, dislocation cells and so forth were formed, which increased the strength and affected the cyclic responses of the material.…”
