Numerical research on kerf characteristics of abrasive waterjet machining based on the SPH-DEM-FEM approach 来自 EBSCO 喜欢 0 阅读量: 188 作者:M Du,H Wang,H Dong,Y Guo,Y Ke 摘要: Abrasive waterjet machining has been widely used because of flexibility, but the cutting accuracy is difficult ...
Prof. Dr. Klaus-G. Hinzen | Universität zu Köln I was new to DEM simulation and had to complete a complex project in a short period of time. ThreeParticle was very easy to pick up and the outstanding expert support from BECKER 3D ensured that we were able to get the most out of...
The SPH method was used to model the fluid phase of debris flow. The DEM was used to model the solid particle phase of debris flow, accounting for the collision–friction effect. The FEM was used to model the flexible barrier, accounting for connections and slipping in a realistic manner. ...
The fluid phase is represented by SPH. The solid phase consists of physical particle(s) and is represented by the DEM, and the deformable structure is represented by the FEM. The interaction forces among the fluid, solid particles, and structure are computed using the penalty function method. ...
SPH particles represented fluid, DEM particles denoted solid immersed in fluid, and FEM elements represented the terrain and structures. The coupling analysis model was used to simulate the coupling contact of solid, liquid, and structures and to describe the entrainment behavior between solid and ...
Rock breaking behaviorMicro-structureMicro-mechanical propertiesIn this study, a two-dimensional SPH-FEM/DEM coupled model is developed to investigate rock breaking behavior under water jet impact based on the LS-DYNA software, where the SPH method is adopted to model the water jet and the FEM/...
Coupled SPH-DEM-FEM approachphysical modelSpillwaySki jumperosionPlunge pools are an economical means for discharging energy flows downstream of dams. However, the high energy discharge usually falls down from a considerable height, which leads to the phenomenon of erosion. The understanding of this ...
