Description
  • This paper introduces a robust numerical tool for modelling of brittle and quasi-brittle interfaces. Such interfaces are characterized by a rapid dissipation of a reversible stored energy which is commonly accompanied by so-called snap-back phenomenon. It leads to numerical instability of standard mathematical approaches. The presented small-strain setting model is subservient to quasistatic processes and individual linear elastic domains are joined by (quasi-)brittle friction-less interfaces. The method of local state is adopted and a current internal interface state is defined by one internal variable - well-known scalar damage parameter. A formal energetic formulation of problem is solved using the Sequential Linear Analysis (SLA). The common discretization of problem by primal variant of Finite Element Method (FEM) is substituted by the Finite Element Tearing and Interconnecting (FETI) method.
