Geomechanics is an interdisciplinary field dealing with the mechanical behaviour of, and fluid flow and transport phenomena in geomaterials (soils, rocks, concrete, ice, snow, powders and ceramics), and their role in diverse applications in geological, geotechnical, structural, earthquake, environmental, mining, offshore and petroleum engineering. The journal emphasizes contributions to the understanding of the complex properties of geomaterials through experimental measurements, and the development or novel use of analytical or numerical techniques to solve problems in geomechanics. Topics of interest in material behavior include instabilities and localization, interface and surface phenomena, fracture and failure, coupled chemo-hygro-thermo-mechanical problems, and time-dependent phenomena. Specifically within the scope of the journal fall the modelling and simulation of heterogeneous materials at different scales, including micromechanics, and any issue that bears upon difficulties encountered in modelling materials where the microstructure becomes important for macroscopically observed mechanical and physical properties. The scope also covers the solution of inverse problems including back analysis of in situ or laboratory tests, and stochastic methods. The journal is particularly interested in contributions that demonstrate the application of theoretical geomechanics in the solution of engineering problems.
