报告摘要：

The seminar presents the mechanics and stress-strain response of sands under cyclic loading. A constitutive model, formulated using the critical state theory within the bounding surface plasticity framework, is proposed which is based an existing model developed at the University of Alberta 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 model has been 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.
