Infill materials found in natural rock joints may cause a reduction in joint shear strength, influencing rock mass stability. This paper reports a study aimed at developing a semi-empirical methodology for predicting the shear<br>strength of infilled joints, ...

Critical state models are highly successful in reproducing the behavior of soft clays as far as the major differences between elastic and plastic behavior are concerned. However, they are not able to model the non-linear behavior of soils at small strains. ...
