Abstract
This paper deals with the stress concentrations of an elastic strip with two pairs of semicircular notches under tension. The method of solution is based upon an application of Green's functions for body force problems of a strip. That is, a principle of the method of solution is to distribute body forces in the interior of a strip with no notches and to determine the intensities of the body forces distributed so as to satisfy the boundary conditions of the notches. Numerical results are obtained systematically for various kinds of notch sizes. An investigation is made for interference effects of stress concentrations due to two pairs of notches and the influences of radii of notches and distance between two pairs of notches on the stress concentration factors.
