Abstract
ABSTRACT The present paper is concerned with the investigation of the inelastic behaviour observed in load-unload cyclic tests performed at 50°C in single lap joints composed of a polyurethane based composite reinforced with fibreglass bonded to an ASTM A1020 steel substrate using an epoxy adhesive. The experiments presented in this research show that the inelastic behaviour of the joint is strongly dependent on the load frequency, eventually leading the structure to exhibit a progressive deformation when submitted to load-unload cyclic loading. The main goal of this study was to propose a preliminary rate-dependent mechanical model capable to describe the cyclic inelastic behaviour for an arbitrary load-unload history at low frequencies and a reasonable agreement was obtained between the experimental results and the model predictions.
期刊介绍:
The Journal of Adhesion is dedicated to perpetuating understanding of the phenomenon of adhesion and its practical applications. The art of adhesion is maturing into a science that requires a broad, coordinated interdisciplinary effort to help illuminate its complex nature and numerous manifestations.
