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

An approximate analytical closed form solution is presented for the st ress field produced in an isotropic, homogeneous infinite plate with t wo unequal, arbitrarily oriented elliptical holes subjected to uniform pressures on the hole boundaries, The problem is formulated in the co mplex plane using the Kolosoff-Muskhelishvili stress functions and fur ther the Schwarz Alternating Method is used to solve the problem of th e doubly connected region. By varying the geometry of the ellipse solu tions to all combinations of elliptical holes, circular holes and crac ks in elastic plates are obtained. The results are computed as stress concentration factors for holes and stress intensity factors for crack s.
