This paper focusses on the numerical computation of the energy release rate for a quasistatic mode-III-interface-crack in 2-D-compounds of strain-hardening alloys. The investigations are made within the framework of deformation theory of plasticity under the assumption of small strains. The material behavior in the plastic region is described by a special power-law, which leads to the p-Laplacian operator, with jumping coefficients on the interface. Existence and uniqueness results for a minimizer of the potential energy referring to the compound are stated. Furthermore, a so called Griffith formula for the calculation of the energy release rate corresponding to the cracked compound is presented and applied to some examples in order to determine this quantity numerically. |
