Abstract: Based on the second-order random wave theory, a joint statistical distribution of the sea surface displacement at a spatially fixed point and its time derivatives of order one and two are derived by using the characteristic ...

Abstract: In this study, the sloped ground subsidence of a jointed rock mass during tilted seam extraction was investigated using a trap-door model and discontinuous deformation analysis (DDA). In the trap-door model, the jointed ...

Abstract: It is well recognized that vorticity and vortical structures appear inevitably in viscous compressor flows and have strong influence on the compressor performance. However, conventional analysis ...

Abstract: A heuristic approach is presented to solve continuum topology optimization problems with specified constraints, e.g., structural volume constraint and/or displacement constraint(s). The essentials ...

Abstract: In a companion paper (2008, “Vorticity Dynamics in Axial Compressor Flow Diagnosis and Design,” ASME J. Fluids Eng., 130, p. 041102), a study has been made on the critical role of circumferential ...

Abstract: The Yuen Long Bypass Floodway (YLBF) was designed to collect flows from the Sham Chung River (SCR) and the San Hui Nullah (SHN) and to serve as a diversion channel of the Yuen Long Main Nullah (YLMN). Under a 200-year ...

Abstract: A three-dimensional (3D) rock slope toppling occurred in a discontinuous rock mass. To simulate the failure process and study the mechanism of this rock failure with contact and large displacement in 3D, a new discrete ...

Abstract: A multilevel adaptive FEM is proposed for multiscale mechanical analysis of heterogeneous materials. The algorithm is developed based on the extended multiscale FEM (EMSFEM), which has been proven to be an efficient method ...
