Modellazione della Non Linearità del Legame Sforzi Deformazioni dei Terreni in Problemi di Sollecitazione Ciclica

This paper critically analyses the capability of simple non-linear models, based on the Masing rules, to fit the experimental stress-strain curves obtained from monotonic and cyclic loading torsional shear tests that were performed on two undisturbed clays and reconstituted sand. A model which modifies the second Masing rule providing more realistic fit of the experimental data is also considered.
