Titanium alloy TC1 and Aluminum alloy LF6 were butt jointed and lap jointed by friction stir welding (FSW), and the influence of process parameters on formation of weld surface, cross-section morphology and strength were studied. The results show that, Titanium and Aluminum dissimilar alloy is difficult to be butt joined by FSW, and some defects such as cracks and grooves are easy to occur. Whe...

A comparison between two known strategies of modeling lap joint interfaces, namely, zero-thickness and thin layer interface theories and their associated updating procedures, is made. Finite element...

this study evaluated the effects of end to end joint types of athel stripes at three level (end to end basic, end to end mitrated and end to end half lap joint) used in core layer veneered with three wood species (fir, beech and oak) and glued with three different ratio of melamine formaldehyde/urea formaldehyde resin (0:100, 25:75 and 50:50) on the bending strengths of bloakboard. according to...

In this paper, three-dimensional modeling of the fatigue crack growth profiles was performed in a simple riveted lap joint. Simulation results showed that mode I was dominated on the one side of the plates and the crack straightly grew on this side, while the other side of the plates was in a mixed-mode condition and the crack propagation path was not straight on this side. Afterward, the fract...

In this study, a penetration-controlled friction stir welding (FSW) technique was employed to lap weld dissimilar Al/Mg alloys, incorporating Zn interlayer. The joint’s microstructure, interfacial reaction, and phase composition were analyzed through optical microscopy, scanning electron X-ray diffraction. findings demonstrate the formation of hybrid joint comprising FSWed region diffusion bond...

In this study, the joining of 6061-T6 aluminum alloy and DP590 steel using a M42 rivet via friction riveting technique is investigated. The surface morphology microstructure characterization reveal formation an anchor zone that imparts mechanical interlock as well metallurgical bonds at interface steel. A combination interlocking bonding results in achievement high load-carrying capacity 5.7 kN...

The joining of dissimilar hard metals such as high-strength steel and nickel-based alloy is required for shipbuilding offshore applications to enhance the strength, fracture toughness, corrosion resistance exposed parts. However, these alloys has remained a major challenge due limited solubility Fe Ni in each other, which commonly results formation brittle intermetallic compounds. We present he...

This paper discusses the static and fatigue behavior of adhesively bonded single lap joints in SMC-SMC composites. Effects of lap length and adhesive thickness on the static and fatigue strength of SMC-SMC adhesive joints are studied. Effects of SMC surface preparation and test speed on the joint performance are evaluated. Finally, the effect of water exposure on the joint durability is also in...
