Abstract
A procedure for optimizing the shape of a biaxial cruciform composite specimen has been demonstrated using finite element analysis. The AS4/3501-6 carbon/epoxy laminate specimen had a layup of [0/90] 105. Eight specimen geometries were analyzed, four having round gage section, while the other four having square gage section. The geometric parameters influencing the stress riser were identified. The gage section fillet was shown to be reaching its optimized value. The effect of changing the gage section fillet on factors such as stress riser, and stress homogeneity was also noted.
