متن کاملDamage Evolution in Composite Bonded Joints under Fatigue Loading
The fatigue behaviour of single lap bonded joints under fatigue loading was already investigated and a suitable life prediction model was presented and validated [1-2]. The model is based on the actual damage evolution under fatigue load: a crack initiation followed by its propagation up to a critical length [2, 3]. In the present paper the evolution of fatigue damage in single lap joints is ex...
متن کاملImproving Fatigue Strength of Welded Joints by Ultrasonic Impact Treatment
Enhancement in fatigue performance of welded joints by Ultrasonic Impact Treatment (UIT) was evaluated with large-scale rolled beam and built-up specimens having yield strength of 345 to 760 MPa. Eighteen rolled-beam specimens having welded details at cover plates and transverse stiffeners and eight built-up specimens having only transverse stiffener details were fatigue tested after treating t...
متن کاملComputational Models of Adhesively Bonded Joints
Simulations using the Finite Element Method (FEM) play an increasingly important role in the design process of joints and fasteners in the aerospace industry. In order to utilize the potential of such adhesive bonding, there is an increasing need for effective and accurate computational methods. The geometry and the nature of an adhesive joint are, however, not so simple to describe effectively...
متن کاملExperimental investigation of mode I fracture energy of adhesively bonded joints under impact loading conditions
Background Recently, the automotive industry has paid attention to multi-material structures to reduce CO2 emission. Hence, the use of light-weight and high-strength materials such as Al–Mg alloys, high-tensile-strength steel and carbon-fiber-reinforced plastics (CFRP) is essential to lighten the vehicle weight [1]. Joining methods for these dissimilar materials are the key to apply them into t...
