N2 - Crack arrays with specific patterns can be found nearly everywhere in nature and play also an important role in structural mechanics. Instead of employing a complicated and advanced numerical investigation, it is useful and often sufficient to estimate energy-release rates and stress-intensity factors of such configurations by simple, engineering-based formulae. To this extend, we improve a previously derived formula with the help of elementary beam theory by accompanying numerical calculations.
