The paper examines the torsion of a solid cylinder composed of a fluid-saturated porous medium with a hyperelastic porous skeleton. The general formulation of the problem is followed with applications to special cases where the strain energy function for the skeletal behavior is described by either a neoHookean or an Ogden-type hyperelastic behavior. The analytical developments involve the numerical solution of the governing equations followed by a computational treatment of the problems using the ABAQUS™ finite element code. The time-dependent mechanics of the twisted cylinder is examined for the instantaneous short-term behavior as well as the long-term behavior when the excess fluid pressures generated during the application of a finite twist have dissipated.

本文研究了由具有超弹性多孔骨架的流体饱和多孔介质组成的实心圆柱体的扭转。问题的一般表述遵循特殊情况的应用，其中骨骼行为的应变能函数由 neoHookean 或 Ogden 型超弹性行为描述。分析开发涉及控制方程的数值求解，然后使用 ABAQUS™ 有限元代码对问题进行计算处理。检查扭转圆柱体的时间相关力学的瞬时短期行为以及在施加有限扭转期间产生的过量流体压力消散时的长期行为。
