In this research, finite element analysis of the conventional drilling and vibration assisted drilling is carried out. The ABAQUS software is employed for FE analysis. The Johnson-Cook models for both plastic deformation and damage are employed for FE simulation.The results of the FE analysis are then verified with experimental results in both conventional and vibration assisted drilling on Al ...

In this research, plasma electrolytic oxidation (PEO) coatings were prepared on 7075 Al alloy in a silicate-based solution with Na2MoO4 additive using unipolar waveform at constant current density. The displayed micro-pores, micro-cracks, pancake-like and crater-like features, also solidified molten oxide particles the surface. majorly composed of Al2O3 (γ, δ, α), SiO2 (amorphous), MoO3 phases,...

Repair of aeronautical structures by composite patch bonding has shown its effectiveness in several studies during the last few decades. This repair technique leads to a retardation propagation repaired cracks via load bridging across throughout adhesive layer, interfacing it with structure. The purpose this study is analyze behavior patch-repaired present thin plates made aluminum alloy 7075-T...

This study investigates the wear performance of Hybrid composite Aluminium Al 7075 (SiC/Al2O3). The Reinforcements used for preparation are Silicon Carbide (SiC) and Oxide (Al2O3). added in 5%, 10% 15% volume percentage to aluminium alloy preparation. developed composites was analysed using dry sliding test apparatus. effect parameters such as load, distance, velocity on response rate were pred...
