The determination of natural frequencies of rectangular plates with mixed boundary conditions by discrete singular convolution

This paper introduces the discrete singular convolution algorithm for vibra tion analysis of rectangular plates with mixed boundary conditions. A unifi ed scheme is proposed for the treatment of simply supported, clamped and tr ansversely supported (with nonuniform elastic rotational restraint) boundar y conditions. The robustness and reliability of the present approach are te sted by a number of numerical experiments. All results agree well with thos e in the literature. (C) 2001 Elsevier Science Ltd.
