Evaluation of the mode I stress intensity factor for a square crack in 3D

Summary, in English

An algorithm for the computation of mode I stress intensity factors of a square crack together with an error estimate is presented. The algorithm is based on a hypersingular integral equation. The leading singular behavior of the crack opening displacement in the corners is taken into account. The maximum value of the normalized stress intensity factor, Fmax, is estimated to Fmax=0.7534±0.0002. Previous investigators have estimated this quantity in the interval Fmax=0.725 to Fmax=0.756.
