Study on the Mechanism of Resonance Inducing V-Shaped Notch Tip Crack

Article Preview

Abstract:

In low-stress precision cropping, a method by which the tiny crack in metal bar V-shaped notch tip can be induced by resonance has been proposed. The critical loading acted on the bar is obtained. The amplitude of bar is calculated under the action of critical loading. The experiments for resonance inducing V-shaped notch tip crack is also carried out. The results show that the V-shaped notch tip can engender tiny crack under the action of resonance force.
