Application of a Spline-Collocation Method to the Problems of Thick Viscoelastic Plate-Strip Vibrations

Authors: Nedorezov P. F.

Vibratory bend of a thick plate-strip with arbitrary edge fixing is considered. The equations of 3D viscoelastic theory in displacements are accepted as governing equations. Boundary problem dimensions reduction is realized with spline-collocation method. 1D boundary problem is solved numerically using discrete orthogonalization method. New effects that cannot be explained with the classic Kirhgof theory are mentioned.
