چکیده
Abstract The objective of the research is to analyze impact ultrasonic vibration assistance on wear resistance due topography enhancement caused Ti6Al4V cylindrical samples after surface modification through a ball burnishing process. process parameters considered for this study are force, number passes, and addition 40 kHz assistance, which thought enhance increase hardener effect in terms depth. A complete screening design 3 factors was performed, revealing that passes most important minimizing volume loss, being 170 N as best combination found. However, no significant difference friction force observed. results show there decrease average roughness from 1.50 0.45 μm with optimal conditions. It also analyzed microstructure originated turning, conventional burnishing, vibration-assisted last depth affectation microstructure. Therefore, these confirm an improvement enhancement, reduction, when added

Free Vibration of Functionally Graded Cylindrical Shell Panel With and Without a Cutout
The free vibration analysis of the functionally graded cylindrical shell panels with and without cutout is carried out using the finite element method based on a higher-order shear deformation theory. A higher-order theory is used to properly account for transverse shear deformation. An eight noded degenerated isoparametric shell element with nine degrees of freedom at each node is considered....

15 صفحه اولGrinding Wheel Loading with and without Vibration Assistance
Introduction Due to its tool structure and composition, the grinding operation is considered the best machining process in the manufacture of brittle materials like ceramics. A grinding wheel distributes wear over many cutters and is capable of replenishing itself. However, the condition of the grinding wheel constantly changes as grits wear and chips accumulate in the spaces between grits. The...
