Web25 de mai. de 2015 · A complete thermodynamic theory is presented that is capable of explaining the dependence of yielding on the degree of saturation in brittle granular aggregates. Historically, constitutive models represented this coupling between mechanics and hydraulics only phenomenologically, by way of the incorporation of the loading … Web15 de jun. de 2001 · ABSTRACT In the seismic analysis of pile foundations the soil is often assumed to be an elastic material and the pressure at the soil pile interface is not limited during the analysis. This may result in a considerable error, as the computed pressure from an elastic analysis may go well beyond the ultimate lateral pressure of real soil. In fact, …
Web25 de mai. de 2015 · Synopsis. The consequences of the assumption that soil is an isotropic, elasto-plastic, continuous medium are examined. A new energy equation is proposed, well supported by experimental evidence, from which a stress-strain relationship is developed for virgin and lightly overconsolidated clays. An alternative stress-strain …
