✦ Synopsis

An analysis is made of the cracked Brazilian disk test. Explicit results are given for the stress intensity factors of a crack aligned at any direction to the applied load. Various approximations are considered and a simplified 'short crack' approximation is shown to be accurate for tela <-0.3 (? is crack length, a the disk radius). At certain angles it is found that crack closure should occur and as a first step the effect of friction is taken into account for such cases by using this short crack approximation. Finally, experimental results are presented to confirm and elucidate the use of this specimen geometry for the problem of combined mode fracture.
