An efficient wave based prediction technique for plate bending vibrations

摘要

The finite element method is a commonly used prediction method for dynamic simulations of plate bending problems. A major disadvantage of this method is its practical frequency limitation as its application involves prohibitively large computational efforts at higher frequencies. A newly developed wave based prediction technique pushes up the frequency limit through an enhanced computational efficiency. This paper discusses the principles of the wave based method for convex plate problems. The beneficial convergence rate of the wave based method as compared with the finite element method is verified for various validation examples, which include the most commonly encountered boundary conditions.
