Simulation of earing of a 17% Cr stainless steel considering texture gradients

A texture component crystal plasticity finite element method (TCCP-FEM) is used for the simulation of cup drawing of a ferritic stainless steel sheet (X6Cr17, AISI 430, EN 1.4016). The simulation includes the through-thickness texture gradient of the starting hot band. It predicts the development of the orientation distribution and the earing profile during cup forming considering 48 slip systems (12{1 1¯ 0}〈1 1 1〉, 12{1 1 2¯}〈1 1 1〉, 24{123¯}〈1 1 1〉). The earing profiles are compared to FE results obtained by use of a Hill 48 yield surface and to experimental data.
