An exact solution for the problem of vibration of a circular plate weakened along an internal concentric circle due to the presence of an angular crack, rotationally restrained and simply supported along an edge of the plate is derived. Frequencies for the first six modes of plate vibrations are computed for varying values of the elastic rotational edge restraint, radius of an angular crack and the...
Incremental forming process is an efficient method for rapid prototyping and low-volume production. Recent ideas have been presented for a new type of this process known as incremental sheet metal hammering method. In incremental sheet metal hammering process, a three-dimensional work piece is produced by only moving a hammering punch over a clamped sheet metal without using a special die. In this...
