- 論文の詳細を見る
The infiltration of a fluid into a dry poro-elastic layer resting on a very porous, rigid foundation and the associated mechanical behaviors, especially the layer compaction and the fluid front moving, were investigated. The solutions were obtained by Landau's transformation and the Crank-Nicolson finite-difference scheme. The numerical calculations are based on the data of material constants for alundum, sandstone, felt, and polyurethane foam. The results are shown in the form of curves and compared in the ab initio fluid-pervaded case. Furthermore, estimates by the incompressible model as well as by the rigid skeleton model are discussed.
