Geological materials (soils, rocks) differ from traditional engineering materials (steel, concrete) mainly due to their discontinuous structure and memory of previous deformation. Description of the mechanical behaviour of geomaterials is thus necessarily related to a number of constitutive models of different complexity. Their overview reflects a concentrated effort to capture various phenomena which can be observed either in the laboratory or in situ. Still, none of the proposed models can take into account all aspects of the mechanical behaviour of geomaterials. Selected examples demonstrate the role of choice of a suitable constitutive model for solving boundary value problems.
