Constitutive Model for Cyclic Behaviour of Cohesionless Sands

This paper presents a constitutive model for describing the stress-strain response of
sands under cyclic loading. The model, formulated using the critical state theory
within the bounding surface plasticity framework, is an upgraded version of an
existing model developed for monotonic behavior of cohesionless sands. With
modification of the hardening law, plastic volumetric strain increment and
unloading plastic modulus, the original model was modified for simulating cyclic
loading. The proposed model was validated against triaxial cyclic loading tests for
Fuji River sand, Toyoura sand and Nigata sand. Comparison between the measured
and predicted results suggests that the proposed modified model can capture the
main features of cohesionless sands under drained and undrained cyclic loading -
