- •
Various computations of N-SIF and derived quantities were carried out by FE analysis.
- •
Different software, element sizes and types as well as refinement strategies were used.
- •
Benchmark study highlighted good agreement of results and potential of N-SIF based approaches.
- •
Meshing and modelling recommendations have been drawn and pointed out.
