This paper is concerned with theoretical analyses of periodic arrays of rigid flat inclusions in solids under uniaxial tension. In the analyses, we choose suitable unit regions, and express the complex stress potentials in eigenfunction expansions in forms satisfying the continuity relations along the inclusion boundaries. The unknown coefficients are determined from the boundary conditions of the unit regions. At this stage, we use a new procedure based on element-wise resultant forces and displacements in order to get highly accurate results. Numerical results of the stress intensity and the tensile stiffnesses of the solids with the inclusions are given for various values of the parameters. The results of the tensile stiffnesses are fitted to reliable polynomial formulae for convenience of engineering applications.
