Geometric and Material Nonlinear Analysis of Three-Dimensional Soil-Structure Interaction
… solid bodies including geometric and material nonlinearities. The formulation also includes the soil-structure interaction effect by using an interface element. A scheme is formulated to allow consistent definitions of stress, stress and strain rates, and constitutive laws. The …

The development of the national accelerator centre proton microprobe as an analytical tool in geochemistry
… trace element microanalysis technique for geological material using protons accelerated by the Van de Graaff Accelerator at the National Accelerator Centre (NAC) in Faure near Cape Town. The method relies on the analysis of Proton Induced X-ray Emission (PIXE) spectra, interpreted with the …

Shock compression and dynamic fragmentation of geological materials
… compression and fragmentation of ge- ological materials with application to blast mining. Two geological materi- als were investigated; Lake Quarry Granite and Gosford Sandstone. Lake Quarry Granite was fully dense, while Gosford Sandstone was porous. The composition and microstructure of the …

Kinetics of microfine cement filtration during constant rate permeation through sands
… the injection of grout into the voids of geological material to improve the engineering properties by reducing the permeability and/or increasing the strength. Permeation grouting can be performed with either cementitious suspensions or chemical solutions. However, over the last several …

Developing methodologies for sustainable groundwater management in sub-Saharan Africa: a case study of the Chad Basin around Maiduguri, Nigeria
… pollution based on the order of their magnitude. Geological material constitutes the lowest risks. Groundwater Physico-chemical analyses result show that the groundwater in the study area ranged from alkaline (pH 6.61-7.57) to slightly alkaline-acidic (6.2-7.31). The distribution of …
