In order to study the stresses working transversely on the square arrays of circular fibers contained in composite materials. strips with a row of circular shaped inclusions subjected to normal loading were studied with respect to the stresses working transversely on the load. The stress distribution was analyzed by the finite-element method, and the results were compared with that obtained by the photoelastic analysis, The results are as follows. (1) It is confirmed that the stresses obtained by the finite-element method agree well with that obtained by the photoelastic method. (2) The maximum stress has been induced at the matrix-reinforcement interface, and the stress concentration factors have increased with increasing constituent stiffness ratio E_f/E_m and with increasing volume content of reinforcement v_f (3) The stiffness of the composite transverse to the axis of the reinforcement has increased with increasing E_f/E_m and v_f.
