请教一下，集中质量为什么还有方向！例如point mass x，rotational mass x。有方向的质量物理意义是什么呀...
To apply the multi-point forming technology to the field of tube processing,the process of multi-point forming for tube is studied.Numerical simulation for the process of multi-point forming for tube is achieved by using elastic-plastic FEM in ABAQUS.During simulation,reasonable coefficient of ...
in order to be sure that the mass scaling magnitude is not too excessive (mass scaling also affects forces, as seen before). Also, artificial energy (which is involved in solving element reduced integration) should be below 1–2% of internal energy. It is observed that the kinetic vs...
ABAQUS software for finite element analysis was used to analyze the phenomenon of stress concentration caused by the drilling and removal of rock mass in vertical well section and radial well section subject to initial stress with the consideration of fluid–solid coupling. The 3D fracture initiation...
Special attention is also devoted to highlighting the computational convenience of implicit MPM modelling in comparison to the explicit MPM. 2 u–p–U formulation for dynamic hydromechanical problems The dynamic response of water-saturated porous media, such as soils, is considered here. The mass ...
Note that in the above equation the external forces at the nodes, fgext, and the global mass matrix, Mg, are constant over the time step as the material points are assumed to deform consistently with the background grid according to the basis functions; that is the value of the basis ...
- 《Finite Elements in Analysis & Design》 被引量: 36发表: 2015年 Modeling Submerged Structures Loaded by Underwater Explosions with ABAQUS/Explicit The behavior of submerged structures due to UNDEX loading consists of added mass dominated low frequency response, high frequency acoustic radiation ...
