چکیده
This paper presents an extensive experimental and numerical study on the behavior of CFRP/Steel adhesively bonded double strap joints (DSJ). A total 50 DSJ specimens were tested under static tensile loading. The digital image correlation (DIC) was used to measure backface deformation. six adhesives that feature different stiffness, strength, ductility, toughness analyzed. parametric including several variants carried out. influencing parameters considered are following: adhesive type, thickness, CFRP elastic modulus, length, surface treatment, steel thickness. results revealed rigid commonly in construction industry do not provide best performance for CFRP/steel joints, instead, tough which combine high strength ductility more suitable strengthening metallic infrastructures. Steel plastic yielding has a significant influence behavior, failure modes joint. model validated with data developed ABAQUS. observations modes, joint strengths, discussed using model. efficiency is highly recommended as design criterion joints.

Experimental 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...
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 and Analytical Investigations of the Dynamic Response of Adhesively Bonded Single Lap Joints
Dynamic response of single lap joints, subjected to a harmonic peeling load is studied theoretically and experimentally. In the theoretical part, dynamic response of a single lap joint clamped at one end and subjected to a harmonic peeling load at the other end is investigated. Adherents are modeled as Euler-Bernouli beams joined in the lap area by a viscoelastic adhesive layer. Both axial and ...
متن کاملPropagation of ultrasonic Lamb waves in adhesively bonded lap joints
This paper considers the bonded joint as a multilayer structure that is analysed using the Transfer Matrix method. In this particular case three layers (two adherents and the adhesive) are considered. The study of this propagation problem may be developed from matrix formulations which describe elastic waves in layered media. This technique combines the theory of the dynamics of the continuum w...
