Abstract: This work aims to study the buckling kinetic process of a piezoelectric thin film (nanoribbon) bonded to a viscoelastic compliant layer with rigid support. The piezoelectric thin film is assumed to be poled in the thickness ...

Abstract: The unloading and reloading of geostress during the excavation of large underground caverns tends to bring about large deformation and failure problems of rock masses with interlayer staggered zones (ISZs), posing significant ...

Abstract: The anisotropic morphology of natural joints always affects their shear behavior. This experimental study aimed at exploring the anisotropic wear damage of asperities for natural joints under direct shearing tests. For ...

Abstract: A lack of joint specimens with the same natural surface morphology has limited detailed experimental study of the shearing performances of joints. In this technical note, we propose a way to batch-produce rock joints with ...

Abstract: Natural joints play an important role in the stability performance of rock engineering. To deeply understand the shear mechanism of natural joints (i.e., tensile fracture or shear fracture), direct shear experiments and ...

Abstract: Jointed rock masses with different orientations and spacings are widely exposed in rock engineering applications, such as underground caverns, slopes, and tunnels, which significantly influence the rock engineering stability ...

Abstract: The uncertainty rock mechanical parameters (i.e., deformation and strength parameters) is an important factor in the safety estimation and support design of underground engineering. Ignoring this uncertainty could allow ...
