摘要：In this study, the experimental and numerical work is presented to study the effect of cut out size, shape, and number on the deflection and stresses in x and y-directions for simply and clamped supported boundary condition of cross and angle-ply laminated plates. The experimental work involved the effect of the cut out size, shape, and number on the deflection and stresses. A comparison study for the deflection and stress results have been achieved between the experimental and those obtained numerically using the finite element method employing ANSYS program Ver. 14. Various support conditions for the plates were adopted with different number of layers and fiber orientations. The shapes of cut out are square, circular, and fillet for different aspect ratios AR=1 and 2. The results showed that the amplitude values of square one are less than that for other types in cross-ply laminated plates and more than that for other cutouts in angle-ply laminated plates for aspect ratio a/b=1. Also the amplitude values of plates with square hole are more than that for circular hole for laminated plates with aspect ratio a/b=2. The stresses increase with increasing of the cutout size, and the increasing of fillet radius decreases the stresses. The comparison study shows a maximum discrepancy of deflection about (9.54%) and maximum discrepancy of stress results about (12.45%).
