By Khalid A. Alshibli, Allen H. Reed

This name discusses a vast diversity of concerns on the topic of using computed tomography in geomaterials and geomechanics. The contributions hide quite a lot of themes, together with deformation and pressure localization in soils, rocks and sediments; fracture and harm evaluate in rocks, asphalt and urban; delivery in porous media; oil and fuel exploration and construction; neutron tomography and different novel experimental and analytical ideas; image-based computational modeling; and software program and visualization instruments.

As such, it will be beneficial analyzing for somebody attracted to the appliance of computed tomography to geomaterials from either primary and utilized perspectives.Content:

2006). To the author’s knowledge, however, the published researches are mainly for dry sand although most of the natural geomaterials are fully saturated or unsaturated porous media. In the present study, strain localization and microstructures in unsaturated sand and clay were investigated using a microfocus x-ray CT. The microfocus x-ray CT system used in this study has very small focus size and has high voltage and current; hence, it is possible to visualize the microstructures in rather larger specimens with high spatial resolution.
