The vibration characteristics depend on a number of factors such as material properties and dimensions of a plate, crack lengths, positions and directions of a crack, and boundary conditions.
The numerical computations were executed on one-quarter of the plate Journal Title and Volume Number (to be inserted by the publisher) 3 with an aspect ratio L/W=2, using four combinations of symmetry and anti-symmetry conditions along the x- and y- axes.

As we shall see shortly, all materials data that relates to the α as well as to the β -phase will be connected in the same manner.
Clearly, the quality of the computer simulations will crucially depend upon the materials data input.
