INTERACTION EFFECTS ON STRESSES IN AN INFINITE-PLATE WITH 2 ARBITRARILY ORIENTED UNEQUAL ELLIPTIC HOLES SUBJECTED TO UNIFORM PRESSURES ON THE HOLE BOUNDARIES

Abstract

An approximate analytical closed form solution is presented for the stress field produced in an isotropic, homogeneous infinite plate with two unequal, arbitrarily oriented elliptical holes subjected to uniform pressures on the hole boundaries, The problem is formulated in the complex plane using the Kolosoff-Muskhelishvili stress functions and further the Schwarz Alternating Method is used to solve the problem of the doubly connected region. By varying the geometry of the ellipse solutions to all combinations of elliptical holes, circular holes and cracks in elastic plates are obtained. The results are computed as stress concentration factors for holes and stress intensity factors for cracks.
