Viscoelastic model to capture residual stresses in heat cured dissimilar adhesive bonded joints

Reliability analysis of bonded joints with variations in adhesive thickness

Residual Stresses in Butt and Socket Welded Joints

A finite element scheme for simulation of welding residual stresses is presented in this paper. Detailed thermal and residual stress analyses for butt-welded and socket-welded pipes are performed using ANSYS and ABAQUS. The calculated distribution of axial stress and hoop stress at welded joint are validated against experimental results. Furthermore, residual stress relaxation under high amplit...

An elastic–plastic interface constitutive model: application to adhesive joints

An interface constitutive model which accounts for both reversible elastic, as well as irreversible inelastic separation-sliding deformations at the interface prior to failure has been developed and implemented in a finite-element computer program. A set of experiments has been conducted to determine the constitutive parameters in the interface model for adhesivelybonded components made from an...

Finite Element Modeling for Thermal Stresses Developed in Riveted and Rivet - Bonded Joints

A three-dimensional finite element modeling is developed using ABAQUS software. This includes riveted and rivet-bonded joints models. Both models undergo thermal heat caused by hot-driven rivet process and then are subjected to a constant velocity at one of its strip edges to simulate the shear tensile test up to the failure point. The developed FE models were based on elastic-plastic propertie...
