Stress analysis of corrugated orthotropic laminates under transverse shear loading

Abstract

This paper presents a study on the stresses caused by transverse shear force on corrugated laminates that complements existing work having addressed stresses caused by bending moment. It recalls recent theory for simulating transverse-force effects, provides fundamental insights on the peculiar effects of corrugation on shear stress distributions, and illuminates the effects of geometric parameters and laminate design on inter- and intralaminar shear-stress distributions. At the end, a critical distance between clamping and transverse-force introduction is identified at which the internal bending moment and the transverse force compete in providing failure conditions.
