Friction stir spot welding (FSSW) is a solid-state process, wherein the properties of weld joint are influenced by state friction and localised thermodynamic conditions at tool-workpiece interface. An issue well-known about FSSW joints their lack reliability since they abruptly delaminate weld-faying interface (WFI). This study explores origins delamination multiple lap welded aluminium alloy (...

This study investigates the strain and stress states in an aluminum single lap joint bonded with a functionally graded Al2O3 micro particle reinforced adhesive layer subjected to uniform temperature field. Navier equations of elasticity theory were designated by considering spatial derivatives Lamé constants coefficient thermal expansion for local material composition. The set partial different...

The continued investigations of the paranormal facilitated development novel theories and methodologies. Psi functioning living deceased in survival phenomena suggested agent psi (LAP) discarnate hypotheses, but neither has demonstrated sufficient explanatory power to claim superiority explaining data. Mediumship studies cannot determine whether information is sourced by means or LAP, presentin...

In this research, the effects of torque tightening on the stress distribution in double lap simple bolted and hybrid (bolted-bonded) joints have been investigated numerically. In order to determine the bolt clamping force value due to tightening torque in simple bolted and hybrid joints, which is necessary in numerical simulation, an experimental approach has been proposed. To do so, two kinds ...

The objective of this paper was to investigate the performance of recessed single-lap joints with dissimilar adherends through the finite element method. The influence of material and geometric nonlinearity of the adhesive as well as the impact of the recess length was examined in terms of maximum principal stresses. The strength of the joint was obtained as the load to initiate the crack propa...

The effects of uncertainties on the strength of a single lap shear joint are explained. Probabilistic and possibilistic methods are used to account for uncertainties. Linear and geometrically nonlinear finite element analyses are used in the studies. To evaluate the strength of the joint, fracture in the adhesive and material strength failure in the strap are considered. The study shows that li...
