Abstract
Stress concentration and strength of uniaxially loaded composite plates containing central circular, elliptical, and square holes are presented. Both smooth and rough holes are considered, as are the effects of relative plate width and thickness. The plates are subjected to static, cyclic, and controlled strain-rate loading. Fracture strength associated with rough holes is slightly lower than with smooth holes, while broad variations in loading history have minimal influence on strength. The tensile stress concentration factor increases and strength decreases as the hole-diameter to plate-width ratio increases. Strength decreases with decreasing ratio of laminate thickness to hole diameter.Keywords
