The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

A practical two-surface plasticity model and its application to spring-back prediction (2007, methodology): “…utilizing a non-quadratic anisotropic yield function and the Ziegler kinematic hardening model (1959), based on the plastic work equivalence principle modified for kinematic hardening to properly define effective (or equivalent) quantities in stress and plastic strain rate (Chung et al., 2005).”
Testing and modelling of material behaviour and formability in sheet metal forming (2014, background): “The Chaboche’s approach was later on adopted and enhanced by other researchers [54,62,86,135].”
