Maximum achievable ultrasonic amplitude depends, primarily, on the properties of the material from which an ultrasonic horn is made as well as on the shape of its longitudinal cross-section.
Due to its high strength and stability in properties, the A7075-T651 aluminum alloy is used as the horn material, its properties are elastic modulus E = 71.7 GPa, Poisson ratio m= 0.33, and mass density r = 2810 kg/m3.
The horn designed by the proposed method will use less material and trial & error time.
