| 英文摘要 | Finite element solution of poromechanical problems often exhibits oscillating pore pressures, if the time step is small relative to the spatial grid size. Here the nonphysical oscillations in the pore pressure are investigated and a novel analytical approach is presented, which satisfies the non-oscillatory criteria for compressible porous medium modeling. With the consistent and the lumped finite element schemes considered, the time-step constraints for three different types of one-dimensional elements are derived in terms of the mesh size and the material properties of both mechanics and seepage. Numerical examples are simulated to illustrate the obtained theoretical results. |
