In this note a new hyperelastic model is proposed to reproduce the nonlinear
anisotropic reversible response of a wide class of geomaterials. The research
is motivated by the non-negligible role played by stress-dependent and anisotropic
elasticity, as combined with plasticity, in the modelling of the mechanical behaviour
of soils and soft rocks under both monotonic and cyclic loading conditions. In fact,
these aspects of the soil response often play a key role in the analysis of many
geotechnical boundary value problems.
