This paper presents an improved soil model based on anisotropic critical state theory and bounding surface plasticity. The anisotropic critical state theory of Dafalias w [...]

The behavior of sand and performance of earth structures are strongly affected by the confining stress. Many existing models for sand are not capable of describing the be [...]

In this paper, a probabilistic analysis in evaluating critical seismic hazard, which refers to the ground motion with zero exceedance probability, was developed. The esse [...]
