The paper deals with the derivation of the analytical solution of a definite elliptical integral of general type which appears in fracture mechanics. The closed‐form solution is expressible in terms of the Gauss hypergeometric series 2 F 1 (a, b; c; z). As an alternative, the authors further present a suitable set of recurrence formulas and the accompanying starting solutions. Their application leads to other closed‐form expressions for the elliptical integral which are offered in the Appendix. Therefore, as a new result, analytical expressions are given for the Gauss hypergeometric series 2 F 1 (a, b; c; z) for specific parameters a, b, c. A powerful algorithm for the numerical computation of 2 F 1 has been developed.
