| 摘 要： | 流变场分配现象在自然界高应变岩石中十分常见。基于Eshelby细观力学理论,结合等效远场方法,建立黏性基质中有限体分比刚性椭球夹杂运动演化的细观力学模型,利用MATLAB程序数值研究流变场速度梯度条件下黏性基质中刚性夹杂的旋转路径,同时给出刚性夹杂的形态演化过程,揭示其运动演化机制。

| Abstract: | Flow field partitioning usually exists in inhomogeneous viscous rocks. Based on the Eshelby micromechanics theory, combined with equivalent far field approach, this work develops a micromechanics model for the motion of a finite volume fraction of rigid ellipsoids in viscous flows. With the MATLAB package, we numerically model the rotation paths of individual rigid ellipsoids under the boundary conditions of velocity gradients of viscous rheology, characterize the geometrical morphology variation and reveal the motion evolution mechanism of rigid ellipsoid |
