Effect of r-value and texture on plastic deformation and necking behavior in interstitial-free steel sheets

Modelling of fracture occurrence in Ti6Al4V sheets at elevated temperature accounting for anisotropic behaviour

“…For the calibration of the damage model reported in §4, the values of the instability strain were also evaluated, namely the values of strain at Ultimate Tensile Stress (UTS) recorded from the experimental engineering stress-strain curves [16] .…”

An Associated and Nonassociated Flow Rule Comparison for AISI 439-430TI Forming: Modeling and Experimental Analysis

“…Chahaoui et al, 2013;Raabe and Lucke, 1993). Therefore, numerous studies have been conducted to improve the formability of ferritic stainless steels by weakening the earing phenomena induced by the crystallographic texture and the resulting elastic-plastic anisotropy of the selected metals (Benke et al, 2018;Beyerlein and Knezevic, 2018;Oh et al, 2017). The main two reasons for Textures occurrence relating to earing are as follows: (i) during thermomechanical processing, continuous recrystallization has been observed (Belyakov et al, 1998;Cizek and Wynne, 1997) , which impedes any texture randomization, and (ii) upon cooling, no phase transformation may occur.…”
