Seismic response of adjacent filled parallel rock fractures with dissimilar properties
a r t i c l e i n f o The purpose of this study is to analytically predict and to experimentally investigate the seismic response of adjacent filled parallel rock fractures with dissimilar properties (e.g., fracture thickness and stiffness). The time-domain recursive method is extended to predict that a P-wave propagates normally across the filled parallel fractures using the specific stiffness...

متن کاملValidation study of the distinct lattice spring model (DLSM) on P-wave propagation across multiple parallel joints
A validation study of the distinct lattice spring model (DLSM) for wave propagation problems is performed. DLSM is a microstructure-based numerical model, which is meshless and has advantages in modelling dynamic problems where stress wave propagation is important. To verify the applicability of DLSM to modelling wave propagation through a discontinuous medium, the virtual wave source (VWS) met...
متن کاملShear wave propagation in jointed rock: state of stress
The mechanical characteristics and orientation of joints determine the behaviour of rock masses, including the strength, the stiffness, and all forms of conduction and diffusion. Furthermore, the preferential orientation of joints renders the medium anisotropic. In turn, these properties affect the velocity and damping of propagating elastic waves. The purpose of this study is to investigate th...
متن کاملSound Wave Propagation in Viscous Liquid-Filled Non-Rigid Carbon Nanotube with Finite Length
In this paper, numerical results obtained and explained from an exact formula in relation to sound pressure load due to the presence of liquid inside the finite-length non-rigid carbon nanotubes (CNTs), which is coupled with the dynamic equations of motion for the CNT. To demonstrate the accuracy of this work, the obtained formula has been compared to what has been used by other research...
