Texture development and plastic anisotropy of b. c. c. strain hardening sheet metals (Q1282694)

A Taylor-like polycrystal model is adopted here to investigate the plastic behavior of body centered cubic (b.c.c.) sheet metals under plane-strain compression and the subsequent in-plane biaxial stretching conditions. The \(\langle 111\rangle\) pencil glid system is chosen for the slip mechanism for b.c.c. sheet metals. The \(\{110\}\langle 111\rangle\) and \(\{112\}\langle 111\rangle\) slip systems are also considered. Plane-strain compression is used to simulate the cold rolling processes of a low-carbon steel sheet. Based on the polycrystal model, pole figures for the sheet metal after plane-strain compression are obtained and compared with the corresponding experimental results. Also, the simulated plane-strain stress-strain relations is compared with the corresponding experimental results.
