Static 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 کاملFatigue Life of Repaired Welded Tubular Joints
In this study, the effect of repair on fatigue life of tubular joints is investigated. Six cracked specimens precedently subjected to fatigue loading undergone to weld repair. Two of those specimens were shot peened before primary fatigue loading. It is shown that repair gives rise to about 150% increase in fatigue life for original specimens while the increase of fatigue life for shot-peened ...
متن کاملFatigue Life Prediction of Rivet Joints
Strength reduction in structures like an aircraft could be resulted as cyclic loads over a period of time and is an important factor for structural life prediction. Service loads are emphasized at the regions of stress concentration, mostly at the connection of components. The initial flaw prompting the service life was expected by using the Equivalent Initial Flaw Size (EIFS) which has been re...
متن کاملFatigue behaviour of composite adhesive lap joints
This paper is concerned with a fatigue study of composite adhesive lap joints produced from a bi-directional woven E-glass fibres and polypropylene. The adhesive used was a Bostik 7452 (Rubber & Plastics Grade) ethyl cyanoacrylate type. The effects of layer orientation, lap joint length and water immersion on the fatigue behaviour were studied. The specimens were immersed in water during period...
متن کاملFatigue 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...
