Measurement of the in-plane shear strengths of unidirectional composites with the Iosipescu test
Measurement of the in-plane shear strengths of unidirectional composites with the Iosipescu test
This paper addresses the issue of the measurement of the in-plane shear strengths of unidirectional carbon/epoxy composites from Iosipescu specimens. A description of the failure of the samples is presented together with finite-element calculations that confirm the observations. This leads to a discussion of the influence of the boundary conditions on failure, supported by both experimental and finite-element analyses. Eventually, it is shown that failure under a homogeneous stress state is achieved, although the presence of parasitic transverse compressive stress complicates the interpretation in terms of in-plane shear strength. It is shown that the use of a quadratic failure criterion leads to the determination of the in-plane shear strength

Abstract
This paper addresses the issue of the measurement of the in-plane shear strengths of unidirectional carbon/epoxy composites from Iosipescu specimens. A description of the failure of the samples is presented together with finite-element calculations that confirm the observations. This leads to a discussion of the influence of the boundary conditions on failure, supported by both experimental and finite-element analyses. Eventually, it is shown that failure under a homogeneous stress state is achieved, although the presence of parasitic transverse compressive stress complicates the interpretation in terms of in-plane shear strength. It is shown that the use of a quadratic failure criterion leads to the determination of the in-plane shear strength
