A model for an anisotropic elastic state

Plasticity and Creep of Metals

“…This section treats the results of experiments in two-axial tension [7,184,185]. On their base, we will make some conclusions about the applicability of theories considered earlier to two-segment loading paths.…”

“…The Zsigalkin-Shemyakin-Christianovich theory [7,184,185] belongs to the concept of slip as well. Those loadings are considered for which the principal directions of stress-and strain-tensor coincide and do not change their orientation.…”
