A unified thermal-hardening and thermal-softening constitutive model of soils
Applied Mathematical Modelling（2019）
Abstract
•Thermo-elastoplastic constitutive model of soil is adopted.•Thermal-induced equivalent stress tensor.•Effect of temperature on the pre-consolidation stress and critical stress ratio is considered.•Thermal-hardening and thermal-softening behavior of soils can be described properly.
