The analysis of adhesively bonded joints started in 1938 with the closed-form model of Volkersen. The equilibrium equation of a single lap joint led to a simple governing differential equation with a simple algebraic equation. However, if there is yielding of the adhesive and/or the adherends and substantial peeling is present, a more complex model is necessary. The more complete is an analysis...

The complex problems of predicting adhesive bond strength for both adhesive and cohesive defects have been studied usinq an ultrasonic, experimental test bed system. This experimental test bed incorporates the ultrasonic and computer equipment necessary to acquire and process data from various types of adhesively bonded test specimens. The computer hardware and software have been developed to a...

Carbon nanotubes (CNTs) are generally considered as a promising particle reinforcement of incorporating advanced properties and characteristics into epoxy nanocomposites. This paper investigated the bonding performances CNT-reinforced adhesively bonded joints on steel substrates using single lap shear (SLS) tests. The (including strength, fracture strain, toughness, failure mode) were studied w...

the use of structural adhesives in automotive structures has been increased recently for their role in noise, vibration and harshness (nvh). therefore, the dynamic behavior of structures containing bonded joints has become an area with numerous investigations over the past decades. development of accurate formulations capable of representing adhesively bonded joint dynamics is a step forward in...

The present study proposes a comprehensive integrity assessment approach for full-scale adhesively-bonded bi-material joint maritime applications. represents cross-section of the bond-line connection ship with steel hull and sandwich composite superstructure. consists core adhesively bonded to two U-shaped brackets. was subjected quasi-static loading profile including 6 load cycles up final fai...

Joints and interfaces are one of the key aspects design production composite structures. This paper investigates effect adhesive–adherend interface morphology on mechanical behavior wavy-lap joints with aim to improve performance. Intentional deviation from a flat joint plane was introduced in different bond angles (0°, 60°, 90° 120°) were subjected quasi-static tensile load. Comparisons made r...

DC electric potential technique has been used to monitor crack growth in conductive materials. A constant DC current is passed through these materials and the crack length is measured through the changes in the electrical voltage at the crack mouth. However, this method is not applicable in crack growth measurement in nonconductive materials or adhesively bonded joints. For these materials, a n...
