Correlating soil properties with post-yield oedometer stress-strain behavior of Finnish sensitive clays through PoYOSS Sen Clay

A novel post-yield oedometer stress-strain prediction model, PoYOSS Sen Clay , was developed at Tampere University, Finland, for Finnish sensitive clays. As a typical characteristic behavior of sensitive clays, in CRS oedometer tests, rapid deformation occurs immediately after yield stress. The post-yield phas...

A semi-empirical framework for interpreting undrained shear strength from piezocone data

Reliable interpretation of piezocone test (CPTU) data in clays remains challenging because conventional empirical correlations with undrained shear strength often rely on cone factors that neglect stress-history effects. This paper presents a unified framework that relates CPTU results to critical state soil mechanics...
