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.
