Abstract: A novel bond-based peridynamic method is proposed to investigate the initiation, propagation, and coalescence of cracks in brittle rock materials subjected to compressive loads. To simulate the failure of brittle rock ...

Abstract: It is assumed that rocks contain three-dimensional (3D) penny-shaped microcracks. The Mode II and III dynamic stress-intensity factors at the tips of 3D penny-shaped microcracks are determined. The orientation angle of ...

Abstract: Geotechnical engineering is dominated mostly by uncertainties, because it always deals with highly variable natural materials. Reliability-analysis approaches emerge as a more reasonable and rigorous way of handling ...

Abstract: The classical Reynolds theory reveals that a converging gap is the first necessary condition to generate a hydrodynamic pressure in a viscous fluid film confined between two solid surfaces with ...

Abstract: The global stability behavior of bird-shaped girders during construction is investigated. The critical torsional buckling moment is derived by the energy method and Galerkin method. Stability design criteria for bird-shaped ...

Abstract: Step-shaped slopes are often found in mines. The reliability of step-shaped slopes was investigated based on random field models. The factor of safety of slopes was derived by the horizontal and vertical integration methods. ...

Abstract: An improved genetic algorithm is proposed to optimize the potential sliding surface of slopes. Compared with a conventional genetic algorithm, the genetic recombination between the previous generation and the newly generated ...

Abstract: In this paper, the antislip stability assessment of a gravity retaining wall is analyzed by considering the spatial variability of soils based on the theory of random fields. The effects of spatial correlation lengths of ...
