✦ Synopsis

Abstraet-Two parallel semicircular surface cracks in a finite plate subjected to nmote tensile loading have been studied. This paper presents an empirical stress intensity factor formula for this crack configuration and the stress intensity factors used to develop the formula were obtained from finite element analysis. The formula covers a wide range of cxmtiguration parameters and is within 6% of the tinite element results. The comparison witb a bi~imensio~ estimation is also considered.
