Cyclic strength
WebJan 1, 2024 · The specimen type of S4, M6 and B6 mainly refer to different notch depths. Based on S4, M6 and B6, specimen types of M10, M15, B10 and B15 are designed to reveal the effect of notch width. Actual section shapes and notch size was checked by Taylor 3D profilometer, as shown in Fig. 2. WebOct 1, 2024 · The cyclic strength of IOFs was a function of moisture content and number of cycles. • IOFs liquefied when the cyclic strength ratio was less than the cyclic shear ratio. • The potential liquefaction zone could be identified by moisture content variation. • The evaluation results agreed with those from dynamic centrifuge model tests.

WebTraditionally, the cyclic hardening/softening behavior is described by the ratio of the ultimate tensile strength to the yield strength or by the strain-hardening exponent (Hertzberg 1989; Mitchell 1989; Landgraf et al. 1969; Manson and Hirschberg 1964 ). Web[1] where represents the applied true stress on the material, is the true strain, and is the strength coefficient. The value of the strain hardening exponent lies between 0 and 1, with a value of 0 implying a perfectly plastic solid and a value of 1 representing a perfectly elastic solid. Most metals have an -value between 0.10 and 0.50.
