摘要

本文提出了多孔弹性材料Biot理论的一个弱公式，用于计算多孔材料非平凡实现的色散特性。该公式考虑了孔隙中固体位移和压力等场变量的周期性，导致了波数的二次特征值问题。

Wave propagation in poro-elastic materials using a shifted cell method for theory of Biot

In this paper, we propose a weak formulation for the Biot theory of poro-elastic materials to calculate the dispersion properties of non-trivial realization of porous material. This formulation considers the periodicity within the field variables which are solid displacements and pressure in pores, resulting in a quadratic eigenvalue problem in terms of wavenumber.
