This dataset contains the UMAT subroutines coded to implement in the finite element code ABAQUS the constitutive models Yld2004-18p (Barlat et al., 2005), CPB06ex2 (Plunkett et al.,2008) and Yld2011-27p (Aretz and Barlat, 2013). They have been used to perform finite element simultations reported in the manuscript of Hosseini and Rodríguez-Martínez. (2021)

Notas
| ** We include different UMATs for2D (plane strain) calculations using the numerical expressions for the yield function gradients proposed by Choi and Yoon (2019).
** The 2D UMATs were used to perform the dynamic necking calculations in Hosseini and Rodríguez-Martínez (2020).
