5. Summary of results

It should be noted that the reference solution is not an exact solution and that it does not apply, in general, in the case of bi-materials. Moreover, the calculations are carried out in non-linear elasticity on a crack; From a point of view, it would be appropriate to perform the elastoplasticity calculations on a notch.

Modeling A (degree 1) gives results in accordance with those of the reference.

Modeling B (degree 2) reveals a difference of around \(\text{8\%}\) on the value of \(G\).

It can be noted that crowns far from the crack provide more accurate and more stable results than those close to the bottom of the crack.
