The principle of effective stress bishop 1959
WebbThe concept of effective stress and its extension from saturated to unsaturated conditions is a subject of interest in the last decades. A simple model for predicting the deformation induced by wetting has been proposed by Casini (2012) considering the variable v v ua (ua uw) (Bishop, 1959) with Sr. WebbThe mo st obv ious practical illustration of the vol-ume change aspect of the principle of effective stress is the continued settlement of a foundation under constant load, due to …
