Analysis of Plasticity and Non-Coaxiality in Geomaterials
A historical review of the institutive models used in geomechanics is presented. The differences between these models originate in either the fundamental mathematical or mechanical principles. The consequences of non-coaxiality of the principal direction of stresses and plastic strain rates is studied with respect to the mechanical formulation and its numerical simulation. The following are detailed: finite element formulation of boundary problems; formulation of double shearing for plasma strain conditions; analysis of double shearing with perfect plasticity; general theory of double shearing; and formulation of double shearing with hardening.
