Abstract

In this paper, stress concentration around a hole is examined in a hybrid composite lamina. Using shear-lag theory, stress concentration factor is calculated and it is shown that its magnitude decreases considerably with an in crease in holes larger to smaller diameters ratio. Compared to a crack, the amount of decrease for an elliptic hole (a / b=2), with eleven broken fibers is 42.5%, if all the fibers are assumed to be of the same type. A decrease in diameters ratio, causes the magnitude of stress concentrations to approach that of a crack. The same behavior is observed for maximum shear stress. According to the results, hybridization has a unique effect on a decrease in both HM fiber stresses and maximum shear stress in the lamina. For N = 31, the decrease in maximum shear stress is 94% at r =11 and a / b = 1.
