Dynamic Problems in Poroelasticity

本研究的重点是解决多孔固体和流-孔界面的基本动力学问题。本文将分析超声现象对流体-孔隙界面的适用性，并确定与孔-流体共振效应相关的散射问题。将研究导波在充液多孔岩石中的传播，以确定孔隙度对导波速度和衰减的影响。多孔介质中的散射将通过在物体中放置圆柱形和球形的不均匀性来考虑。本研究结果将有助于评估利用孔隙弹性现象分析微观结构对含微裂纹的岩石和复合材料等多孔结构有效弹性模量影响的可行性。

This research is focused to resolve fundamental dynamic problems in porous solids and fluid-porous interfaces. The applicability of ultrasonic phenomena will be analyzed for a fluid-porous interface and scattering problems related to pore-fluid resonance effects will be determined. Wave propagation in a fluid-filled porous rock will be studied to determine the effect of porosity on velocity and attenuation of guided waves. Scattering in porous media will be considered by placing cylindrical and spherical inhomogenities in the body. The results of this research will help to assess the feasibility of using poroelastic phenomena to analyze the role of microstructure on effective elastic moduli of porous structures such as rocks and composite materials containing microcracks.
