The Journal bridges the gap between constitutive modelling and the solution of engineering problems in the field of geo-materials and structures. The Editors aim to foster the exchange and dissemination of new ideas and results between engineers doing research on geomaterials (soils concrete rocks) and related materials (such as powders and ice) including applications to structures. In this light the emphasis of the journal will be on experiments (both in-situ and in the laboratory) constitutive modelling interface and surface phenomena instabilities fracture and failure inverse problems coupled deformation-diffusion processes time-dependent phenomena and development of numerical techniques needed for large-scale computations. Specifically within the scope of the journal fall simulation and modelling of the mechanical behaviour of heterogeneous materials at different scales including micro-mechanics and any other issue that bears upon the specific difficulties encountered in modelling materials where the microstructure becomes important for their macroscopically observed mechanical and physical properties. Applications may be to any area of geotechnical mining environmental and structural engineering. E.g. reinforced systems (geotextiles reinforced concrete) construction processes earthquake engineering reservoir engineering off-shore technology geo-thermal energy earth-structure interaction are within the scope.
