Abstract
Starting from a mixed modelling of a matrix material reinforced by regularly embedded inclusions regarded as straight beams, and through a homogenization procedure making use of the virtual work method, a micropolar description is obtained for the homogenized composite medium. The model is implemented within the context of the yield design theory, the strength properties of the reinforced matrix material being simply deduced from those of its individual components. The upper bound kinematic method is then applied to the stability analysis of a reinforced vertical excavation.
