Basically, the rock and rock-like materials such as concrete and soil are considered as geomaterials. Clays and some other materials which can be related with engineering processes can, also, be included in this category. Geomaterials are essential for life since human construct storage and access/transport areas in r…

It is shown that on a small (200 km 2 ) massif area two extensive groups of metallic (Cr, Ni, Cu, Au, Ag, Pt, Pd, Ru, Os, Ir) and non-metallic (diamond, nephrite, jewelry and ornamental rodingites, chrysolite) types of minerals are spatially and genetically c…

In order to make the use of complex elasto-plastic behavior models more accessible, we attempted to identify the Cam-Clay model in two samples of tropical and lateritic soils (from Senegal/West Africa) from casagrande box shear and oedometric tests. This meth…

It is now recognized that many geomaterials have nonlinear failure envelopes. This non-linearity is most marked at lower stress levels, the failure envelope being of quasi-parabolic shape. It is not easy to calibrate these nonlinear failure envelopes from tri…
