Dynamics of Composite Materials and Elastic Structural Elements with Variable Dimensions.

Abstract

The project was concerned with the development and exploitation of new methodologies for an effective and accurate calculation of the dynamic response and overall properties of elastic composites with periodic structures, and vibration of elastic structural components which have relatively large variations in their stiffness, mass distribution, and/or dimensions. The work accomplished is in the areas of waves in layered and fiber-reinforced anisotropic elastic composites, stability and dynamic response of rotating blades; and overall properties of composites with periodic structures. The results have been reported in nine papers, which have been (or will be) published in the scientific literature. (Author)
