Analysis of the Iosipescu Shear Test as Applied to Unidirectional Carbon-Fibre Reinforced Composites 

 -  Composites Science and Technology, 38(4), p.299-325, 1990 .
<br/><br/> In tralaminar shear properties of unidirectional carbon-fibre reinforced epoxy and PEEK composites were #westigated using the Iosipescu shear test. The apparent shear strength and shear moduli were measured using specimens with two different fibre orientations. Finite element analysis was applied to determine the stress distribution within the losipescu specimen. Using numerical correction factors to account for the non-uniform shear stress distribution in the gauge-section of [osipesc,t specimens, the actual shear moduli were established. The Iosipescu shear test also provided a reasonable esthnate of the shear strength.
