Y. Liu et al., Investigation of a Zienkiewicz-Pande yield surface and an elastic-viscoplastic boundary element formulation, ENG ANAL, 24(2), 2000, pp. 207-211
This paper investigates a general yield surface originally proposed by Zien
kiewicz and Pande. Some useful modifications are made for two classes of yi
eld surfaces (hyperbolic and elliptic), and the elastic viscoplastic bounda
ry element formulation for incorporating the model is presented. (C) 2000 E
