Effect of Gage-Section Size on Composite Stiffness Measurements

Abstract

The stiffness of engineering materials is typically calculated using a strain value recorded from a gage mounted on test coupons of the material. In heterogeneous materials, such as fiber reinforced composites, the measured strain used to calculate stiffness may depend on the size of the gage section, i.e., the area over which the strain is measured.
