| 摘 要： | 在经典单相Timoshenko梁变形和孔隙流体仅沿多孔梁轴向运动的假定下,基于不可压饱和多孔介质的三维理论,论文首先建立了横观各向同性饱和多孔弹性Timoshenko悬臂梁拟静力弯曲的一维数学模型,并给出了相应的边界条件.其次,利用Laplace变换及其数值逆变换,分析了端部不同渗透条件下,饱和多孔弹性Timoshen...

| Abstract: | Based on the three-dimensional theory of incompressible saturated porous media,a one-dimensional model for quasi-static bending of a transversely isotropic saturated poroelastic Timoshenko cantilever beam is established with assumptions of both deformation of single-phase beam and movement of pore fluid only in the axial direction.The corresponding boundary conditions are presented,too.The quasi-static bending of the saturated poroelastic beams subjected to a step load at its free end,with different end per... |
