Understanding mechanical interactions at the root-soil interface is essential to predict erosion of vegetated slopes. Recently, shear strength vegetatedil under changing hydraulic conditions has been measured and modeled; however, interfaces have not investigated conditions. This paper proposes (1) a novel pullout apparatus measure suction, (2) Mohr-Coulomb-Vilar (MCV) model interfaces, (3) num...

The direct application of the Hoek–Brown failure criterion to practical slope engineering is still an urgent problem. geometries and earthquake effect need be considered in determination linear Mohr–Coulomb (MC) strength parameters from criteria for stability analysis. This study adopted tangential method construct a three-dimensional (3D) rotational mechanism using homogeneous rock slopes unde...

The mechanical properties of methane hydrate are important to the stability of borehole and methane extraction from a methane hydrate reservoir. In this study, a series of triaxial compression tests were carried out on laboratory-formed methane hydrate-ice mixtures with various methane hydrate contents. Axial loading was conducted at an axial strain rate of 1.33%/min and a constant temperature ...

It is widely known that rainfall induces a rise of the groundwater level and an decrease in matric suction (negative pore water pressure) that results in slope failure. However, in many situations where shallow failures are concerned, it has been noted that there is not much evidence of a rise in the groundwater level sufficient to trigger the observed slope failures. Instead, the failures have...

Statistical mechanics has provided powerful techniques to measure mechanical properties of materials at the nanoscale and paved the way for bottom-up computational materials design. The introduction of such techniques in civil engineering applications, namely construction and geotechnical materials, remains limited to the elastic and fracture properties. This paper presents an atomistic approac...

Multi-layered plates consisting of DH-36 steel coated by a thick layer of polyurea, for increased blast and impact protection, are of increasing importance to the Department of Defense. A hybrid approach of experiments and simulation was performed to characterize fracture and plasticity of DH-36 Navy steel, which is the first step in creating an accurate model of the composite material. The per...

ABSTRACT: Liquefaction-induced lateral spreading of soils caused by strong shaking requires careful evaluation to be properly accounted for in geotechnical, and structural design of strategic infrastructure located in highly active seismic coastal regions. Although a large number of empirical and semiempirical models are available, there is still a lot of inconsistency in their predictions. In ...
