    This note explores the influence of environmental effects, as those induced by cyclic changes in relative humidity, on the degradation of the shear strength parameters in Lilla claystone, a low-porosity clayey rock from ...
  • Small strain shear moduli of unsaturated natural and compacted loess 

    Ng, C. W. W.; Kaewsong, R.; Zhou, C.; Alonso Pérez de Agreda, Eduardo (Thomas Telford, 2017-07)
    Accés restringit per política de l'editorial
    Suction and microstructure play critical roles in the mechanical behaviour of loess, yet their effects on small strain (from 0·001 to 1%) shear moduli are not fully understood. In this study, shear moduli of loess with ...
