Rotary ultrasonic machining is a cost-effective and precise method for hard brittle materials. Aiming at processing SiCp/Al composites, rotary grinding spindle proposed in the present study. Expressions were established to calculate displacement, rotation angle, bending moment, shear force of vibrating elements based on Mindlin moderately thick plate theory. Combining continuous boundary condit...

Metal matrix composites (MMCs) have become attractive for engineering structural applications due to their excellent specific strength property and are increasingly seen as alternative to the conventional materials particularly in the automotive, aerospace and defence industries. Al/SiC MMC has aluminium matrix and the silicon carbide particles as reinforcements and exhibits many desirable mech...
