Abstract
The limiting value of the stress-concentration factor at the edge of a large hole in a tensile strip as the hole diameter, a, approaches the strip width, w , has been investigated by many researchers. They made use of several theoretical, experimental and numerical techniques. There are two different solutions for the value of the stress concentration factor based on the net stress, Ktn , They are: Ktn= 1 and ktp = 2. For this paper, the problem is analyzed by the boundary element method. A complete set of models with a/w = 0.4-0.99 is analyzed. The results indicate that the stress concentration factor is near two.
