DOI: 10.1016/j.compgeo.2019.02.024
Abstract: Abstract A unified model for clays and sands, referred to as CSUH model, is proposed. The CSUH model develops the following aspects based on the unified hardening (UH) model: (a) a curved normal compression line… read more here.

DOI: 10.1016/j.ijplas.2018.06.013
Abstract: Abstract This paper proposes a kinematic hardening model to capture both asymmetric plastic behavior (early-reyielding, transient Bauschinger effect and permanent softening) and directional hardening (anisotropic hardening) response at the same time. The previously reported kinematic… read more here.

DOI: 10.1177/1687814017750680
Abstract: A detailed understanding of the constitutive behavior of AH36 material in continuous casting process was obtained through various high-temperature tensile testing at specific ranges of temperatures (1173–1673 K) and strain rates (10−4−10−2 s−1) using a Gleeble system.… read more here.
