2. Benchmark solution

2.1. Calculation method

The reference solutions for stress intensity factors come from Murakami’s « Stress Intensity Factors Handbook » [bib1]. The reference solutions for error estimation are non-regression solutions. The error estimators were validated in the thesis of J. Delmas [bib2].

2.2. Reference quantities and results

The reference results for stress intensity factors are:

	\({K}_{I}\)	\({K}_{\mathrm{II}}\)
Problem 1	9.37
Problem 2	33.93	4.53
Problem 3	6,33	1,86
