Aging aircraft may develop multiple-site damage (MSD) that can reduce the structural integrity of fuselage structures. The existence of small cracks emanating from adjacent rivet holes in a fuselage lap-splice joint is of major concern. Small collinear cracks greatly reduce the residual strength of a panel with a lead crack. Recent studies predicting the residual strength of flat and curvilinea...
In this research, friction stir joining of aluminum-polypropylene/talc composite was investigated due to the numerous applications aluminum-polymer joints in automotive and aerospace industry. A novel tool design, including a rotary/stationary holder, used improve appearance mechanical performance lap by preventing mixed molten polymer aluminum particles from exiting stirred zone. Effect transv...
joining of titanium alloys to other materials especially steels has attracted much attention in recent years due to the exceptional properties of titanium such as excellent corrosion resistance and mechanical properties and its increasing application in various industries. according to the fe-ti binary phase diagram, these two elements do not have complete solubility. this leads to difficulties...
The recent increase in the use of adhesively bonded joints (ABJs) made from dissimilar adherends demands acquisition a better understanding strength and behaviour these joints, including their failure mechanisms. Several studies have reported on such individually, however few compared performances ABJs with varying configurations design parameters, order to determine optimal configuration for h...
To obtain a high-quality Al/steel dissimilar joint, micro-groove-assisted vortex-friction stir lap welding (MG-VFSLW) process was developed. Through prefabricating micro-grooves on the steel plate surface by laser ablation, mechanical interlock and metallurgical bonding were obtained simultaneously in MG-VFSLW process. The weld formation, interface microstructure, properties, failure mode studi...
بررسی تاثیر فاصله توقف جوشکاری انفجاری بر ساختار و رفتار خوردگی اتصال آلومینیوم 5083- مس در محیط نمک
In the present study, the effect of explosive welding stand-off distance on the structure and corrosion behavior of aluminum alloy 5083-copper joint is studied. The microstructure was examined by optical microscopy and scanning electron microscopy and corrosion behavior with poteniodynamic polarization tests and electrochemical impedance spectroscopy in a salt environment. Microscopic results s...
In this paper, influence of riveting process parameters, namely, riveting force, sheet thickness, friction coefficient and clearance fit are investigated on residual stress field and fatigue life of single riveted lap joint of AA2024 type. According to the effect of riveting induced residual stresses on fatigue life of riveted lap joint, these parameters are optimized to maximize the residual s...
In this study, analytical models considering different material and geometry for both single and double-lap bolted joints were reviewed for better understand how to select the proper model for a particular application. The survey indicades that the analytic models selected for the adhesively single or double bolted lap joints, as well as T, scarf, and stepped joints, with linear material pr...
