Measurement of shear deformation behavior in thickness direction for a mild steel sheet

Abstract

Abstract. The anisotropy parameter of the through-thickness shear for a hot-rolled mild steel sheet was determined by comparing the measured and simulated deformation behaviors. A tensile test using a strip specimen with a stepped shape in the thickness direction to apply the through-thickness shear deformation at the center of the specimen was conducted. Finite element analyses were performed by changing the anisotropy parameter M of the Hill ’48 yield function. The measured through-thickness shear strain γ_zx was compared with the simulated one to identify the parameter M. In addition, plate compression simulations were performed to evaluate the effect of the through-thickness shear anisotropy on the deformation behavior during plate compression.
