Due to the interstitial fluid between the partials , the solutions of the pressure and tangential force between the two granules are the theoretical foundation of the wet granular discrete element method 当颗粒之间有法向或切向相对运动时,由于存在填隙流体,颗粒之间产生的法向的挤压力和切向阻力,是湿颗粒离散元法的理论基础。
The discrete element method ( dem ) is a powerful tool in analyzing granular assembly . the granular discrete element method can be applied to the partials , whose shape can be approximately described as a sphere 离散元法( dem )是分析散体力学行为的数值方法,颗粒离散元法适用于单个几何形状可用圆球近似而不产生显著差异的情况。
In this paper , the state of history and present for discrete element method are reviewed and summarized . extended element models are presented by extending on motohiko hakuno and noriyuki utagawa existing models 本文回顾和总结了离散单元法的发展历史及其研究现状,对现有模型进行了扩展,提出了基于motohikohakuno的改进单元模和基于noriyukiutagawa的改进单元模型。
In consideration of the penetrative cranny in the soil , the volumetric strain model was established by discrete element method , according to the strains of penetrative marine soft clay and the volumetric strain , based on the definition of permeability and porosity , dynamic models of physical parameters were established 结合土颗粒和土体骨架应变,从土的孔隙率和渗透率的定义出发,推导出沉贯过程中筒内海积土物性参数的动态模型。
I believe that the world of industrial products , especially those which come in contact with the human body , this includes architecture , will be quite similar to the organic creations of nature without rigid geometry , sharp corners or discrete elements 我相信未来世界里的工业产品,尤其是那些和人类身体直接联系的,包括建筑在内,将会和自然界的有机生命体相当类似,将不再会是今天这样由刚硬的几何线条、尖锐的角度和不连续的元素来支配。
