Optimal Shear Correction Factors in Hierarchical Plte Modelling

Abstract

This paper addresses the formulation of hierarchical plate models as an optimal (in a clearly defined sense) numerical method which can be easily implemented and is available in the code MSC/PROBE. Special emphasis is placed on the optimal selection of the shear correction factors. It is shown that different measures of accuracy lead to different optimal choices of these factors. The main tool in the analysis is the Fourier transformation.
