✦ Synopsis

Ahatract-Two equal parallel cracks on one edge and one unequal parallel crack on the other edge of a Ii&e width sheet are studied. Formulae for calculating the stress intensity factors @IF) of this crack contiguration are obtained from the results of finite element analysis. The difference between the formulae and the finite element results is less than 3%. Gn this basis, the influence of crack interactions on SIF is discussed.

Abstrac-Two and three parallel cracks in a finite sheet subjected to remote tensile loading have been studied. This paper presents empirical stress intensity factor formulae for these crack configurations. The stress intensity factors used to develop these formulae were obtained from finite element
