        Analysis of shear stress wrinkling of asymmetric sheet specimen under offset loading

        Haoxing Tang,Tong Wen,Jiewei Hong,Yin Zhou,Longzhu Zhang 대한기계학회 2022 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.36 No.3

        The commonly used wrinkling evaluation methods such as cup forming and the Yoshida buckling test (YBT) only consider the symmetric sheet specimen and loading, therefore a deviation from the reality is inevitable. A method using the asymmetric specimen (AS) under offset loading is proposed and investigated with two materials SUS304 and DC04. Results show that the unbalanced external force in AS induces special stress state that is not included in YBT at wrinkling onset, where the shear stresses are dominant. The length and height evolution of the wrinkle is controlled by the principal stresses, and the direction gradually approaches the tensile axis during deformation. The shear stress decreases with the length/width ratio increases, but it rises at first and then falls when the clamping width increases. The error between the simulation and experiment is 2.9 %. This method can be used to examine the shear wrinkling properties of sheet metal.
