Abstract
The ubiquitous nature of porous materials makes them an important class of engineering materials. The study of mechanics of porous materials dates back several decades. Several theories of first-order have been proposed for
porous materials. The first-order models have been successful in predicting the behavior of porous materials in many scenarios. However, it has been observed in experiments that if the length scale of the heterogeneities of porous materials is of order of the size of sample of the porous materials, the first-order models fail to predict some important material behaviors. Firstorder models also fail to predict boundary layer effects in standard problems such as Terzaghi’s consolidation problem and Mandel’s problem. The aim of the doctoral project is to develop a higher-order multi-scale model for porous materials. In the first half of the doctoral project, we have developed a second-order phenomenological model for porous materials. In the second half of the project, we aim to extend the model to include dynamic effects. We further aim to extend the model to include fracture.
