A rectangular array and a zig-zag array of rigid short flat inclusions in an infinite solid subjected to biaxial tension are considered in this paper. In the analyses, we take a rectangular unit region and a triangular unit region, and express complex stress potentials by eigen-function expansions in forms satisfying the continuity relations along the inclusion boundaries. The unknown coefficients are determined from the boundary conditions in the unit regions which are expressed in terms of the resultant forces and displacements. Numerical calculations are carried out for various combinations of inclusion length and inclusion space. The stress intensity factor and the tensile stiffness for the solids that contain inclusions are represented in figures. The results of the tensile stiffness are fitted to polynomial formulae. They are useful to the design of the composite materials.
