The newly developed Yeh-Stratton (Y-S) Strength Criterion was used to study the failure of composite materials with central holes and normal cracks. To evaluate the interaction parameters for the Y-S failure theory, it is necessary to perform several biaxial loading tests. However, it is indisputable that the inhomogeneous and anisotropic nature of composite materials have made their own contri...

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...

Background: This study presents a numerical solution for determining the limiting uniform normal pressure acting horizontally behind cohesive-frictional backfill material in deep contiguous piled wall. At this pressure, soil tends to flow out gaps between series of vertical piles placed at certain horizontal spacing. Methods: The lower and upper bound plane strain finite element limit analysis ...

Abstract Study of mechanical properties rock under hydro-mechanical coupling. The MTS815 mechanics system is used to perform triaxial compression tests water-saturated sandstones different confining pressures and pore water pressures. results show that the peak deviation stress its corresponding axial strain, residual stress, initial dilation deformation modulus sandstone are related pressure p...
