    A Numerical Approach to Imperfect Interfaces with Initial High Stiffness

  • Original language description

    Our approach attempts to eliminate the well known problems in the modelling of interfaces with initial high stiffness. It is a rate-independent energybased model which uses the principles of isotropic damage mechanics to modelling of an interfacial damage evolution. A mixed-mode constitutive model with linear softening, based on the developments of Ortiz and Pandolfi, is implemented. The continuous formulation is converted to the time-incremental problem, which is subsequently discretized using the FETImethod. Finally, the resulting optimization problem is minimalized via the alternate minimization strategy due to Bourdin.
