Fatigue Crack Growth in Adhesive Joints
Adhesive joining is recognized as a potential enabling technology for a variety of material systems being considered in automotive structures where traditional fastening methods would be inappropriate. Well known examples include fiber reinforced composites and polymers. Additionally in certain circumstances, adhesive bonding of steel structures can provide benefits such as improved stiffness a...
متن کاملStatic and Fatigue Behavior of Adhesive Joints
This paper discusses the static and fatigue behavior of adhesively bonded single lap joints in SMC-SMC composites. Effects of lap length and adhesive thickness on the static and fatigue strength of SMC-SMC adhesive joints are studied. Effects of SMC surface preparation and test speed on the joint performance are evaluated. Finally, the effect of water exposure on the joint durability is also in...
متن کاملQuasi-Static Crack Propagation by Griffith’s Criterion
We consider the propagation of a crack in a brittle material along a prescribed crack path and define a quasi-static evolution by means of stationary points of the free energy. We show that this evolution satisfies Griffith’s criterion in a suitable form which takes into account both stable and unstable propagation, as well as an energy balance formula which accounts for dissipation in the unst...
متن کاملCrack propagation across an adhesive interlayer in flexural loading
Crack propagation across interlayers separating adjoining brittle plates in flexure was studied using a model glass/epoxy/glass system. A transverse starter crack in the center glass plate was made to propagate to the nearest epoxy interface, where it arrested. System failure occurred at some higher load by crack reinitiation from pre-existing flaws in the adjoining glass surface, not by contin...
متن کاملLifetime prediction of adhesive joints subjected to variable amplitude fatigue
Almost all structural applications of adhesive joints will experience cyclic loading and in most cases this will irregular in nature, a form of loading commonly known as variable amplitude fatigue (VAF). This paper is concerned with the VAF of adhesively bonded joints and has two main parts. In the first part, results from the experimental testing of adhesively bonded single lap joints subjecte...
