2. Benchmark solution

This test case is a case of non-regression. The solution compared to here is obtained using a Python development version of the command, which made it possible to develop the \({G}_{p}\) approach.

The notch bottom is elliptical in shape. This is described by slices. Each slice consists of chips. This total chip zone corresponds to the virtual propagation of the notch.

Slice n

Band N+1

Chip 1 from Tranche N

Notch background

In each chip and at each moment, the evolution of the quantity \({G}_{p}(\Delta S)\) defined by:

\({G}_{p}(\Delta S)=2[{W}_{\mathit{elas}}^{\mathit{traction}}(\Delta S)]/\Delta S\)

where \({W}_{\mathit{elas}}^{\mathit{traction}}(\Delta S)\) is the elastic tensile energy calculated on the cumulative chip zone according to a slice.
