| 英文摘要 | A two-scale computational homogenization model is presented for modeling three-dimensional (3D) heterogeneous poro-elastic media in the framework of the Numerical Manifold Method (NMM). The micro-dynamics is fully incorporated using the extended first-order Hill-Mandel principle for simulation of the hydro-dynamic response. The micro -and macro-scale Initial Boundary-Value Problems (IBVPs) are simultaneously solved with the NMM by exchanging quantities between different scales. The micro-scale IBVPs are solved under both Linear Boundary Conditions (LBCs) and Periodic Boundary Conditions (PBCs). The macro-scale IBVP is solved using the Newton's algorithm iteratively. For both micro-scale LBCs and PBCs, highly efficient algorithms for extracting macro-scale quanti-ties and Jacobian matrix from the micro-scale are established merely by simple matrix manipulations of the micro-scale Jacobian matrix without solving any IBVPs. By conduct-ing benchmark simulations of the heterogeneous porous media under uniform, partial and impact loads, the accuracy, stability and versatility of the presented multiscale model are verified.(c) 2022 Elsevier Inc.
