Abstract
A series of experiment were programmed on the effect of ultrasonic vibration on the compressive deformation of metals. For this purpose, an apparatus has been devised. In this report, the outline of the apparatus and some analytical results of various factors involved are given.
The ultrasonic vibration is generated by a magnetostrictive nickel transducer, and is superimposed on a static compressive load through horns in the form of resonance oscillation. The frequency and the amplitude transferred to a specimen are about 22 KC and up to about 17 μ, respectively. Analysis has been made for the factors, which would affect the vibration mode or the deformation behaviour, such as specimen size, static load, vibrational stress, amplitude, acceleration and heat generation, etc. Some data of a preliminary experiment are also described.
