Refinements in the Approximate Analysis of Web-Stiffened Sandwich Structures.
Abstract
Present in this work is a method of construction of approximate functions in connection with the energy formulation of certain eigenvalue problems of web-stiffened sandwich structures. The construction is based, upon the method of Young together with a group of fundamental functions deduced from Timoshenko's flexural equations for elastic beams. The analysis is exemplified and numerically tested by the eigenvalue problems of free vibrations and buckling of one-dimensional sandwich structures. Results indicate that the present method possesses marked advantages over similar constructions oriented from the classical flexural normal modes of Bernoulli-Euler. (Author)
