Bounding surface crushing soil model

Dec 01, 2014 A bounding surface plasticity model is presented for crushable rockfills in the framework of the critical state soil mechanics which includes translation of the critical state line due to particle crushing. A translating limiting isotropic compression line is also introduced and incorporated in the model to describe the position and evolution

    Jan 25, 2011 Jan 25, 2011 A new bounding surface constitutive model for sands is presented and is suited to a wide range of stresses, including those sufficient to cause particle crushing. The basic concepts of critical state soil mechanics are shown to be valid, and a uniquely shaped critical state line is defined to capture the three modes of plastic deformation

    Sep 07, 2005 A unified constitutive model for unsaturated soils is presented in a critical state framework using the concepts of effective stress and bounding surface plasticity theory. Consideration is given to the effects of unsaturation and particle crushing in the definition of the critical state. A simple isotropic elastic rule is adopted

    method is to use bounding surface plasticity as applied by Yu et al. [10, 11]. To our knowledge, the only model for unsaturated soils using bounding surface plasticity was developed by Russell and Khalili [8]. However, this model took into account particle crushing, making it complex and difficult to be applied to ordinary cases in soil mechanics

    Apr 04, 2021 Apr 04, 2021 To describe the drained behaviors of cohesionless soil through a concise constitutive approach, a single-surface model is constructed on the concept of the bounding surface. Based on observations from tests, the maximum prestress memory surface and the radial mapping rule are adopted to take the effects of loading history into consideration

    Jul 16, 2020 Jul 16, 2020 This paper reports a new bounding surface model for saturated and unsaturated interfaces. New formulations were developed to incorporate suction effects on the flow rule and plastic modulus. To examine the capability of the proposed model, it was applied to simulate suction‐ and stress‐controlled direct shear tests on unsaturated soil

    Sep 24, 2011 A 3D bounding surface model is established for rockfill materials, which can be applied to appropriately predict the deformation and the stabilization of rockfill dams. Firstly, an associated plastic flow rule for rockfill materials is investigated based on the elaborate data from the large-style triaxial compression tests and the true triaxial tests. Secondly, the constitutive equations of
