7. Summary of results

The calculation of \({K}_{I}\) and \({K}_{\mathit{II}}\) is not available for a crack located at the interface of a bimaterial, and the comparison is therefore made directly on the energy recovery rate \(G\).

The calculation of \(G\) is not accurate on the first corona in all cases of crack inclination, which confirms that it is necessary to avoid taking a zero radius \(\mathrm{Rinf}\). For the other crowns, the differences are of the order of 0.4%. For the case of inclination \(\theta =60°\) the difference exceeds 1%. Overall, the results are satisfactory for \(G\).
