✦ Synopsis

The elastosatic problem solved in this paper is of an isotropic homogeneous infinite plate, with two arbitrarily oriented cracks of different lengths, subjected to uniform uniaxial tension at infinity. The problem is formulated in the complex plane using the Kolossoff-Muskhelishvili stress functions and further the Schwarz's alternating method is used to solve the problem of the doubly connected region. The mode I and mode II stress intensity factors at all the four crack tips for various crack length ratios, crack angles and crack spacings are found, and are in good agreement with those obtained by other research workers. The fracture angles at the four crack tips are evaluated using the strain energy density theory and maximum tangential stress theory. The minimum strain energy density factor is also found at all the tips.
