Analysis of 3D-reinforced composite annular plate subjected to concentrated forces

Abstract

Abstract This paper is dedicated to the solution of the problem about 3D-reinforced composite annular plate compressed by concentrated forces. 3D-reinforced composite materials, including high-temperature composites, are widely used in modern space industry, while their properties are insufficiently studied. Analytical solution of considered problem about annular plate compression will be a foundation for a method of determination of anisotropic composite materials stress-strain properties needed when conducting structural analysis: elastic and shear moduli, and Poisson’s ratio. Transverse shear deformations and changes in annular plate metrics during deformation are taken into account in the process of finding analytical solution of the problem. The analytical solution of the problem about annular plate compression was obtained by the authors. This solution is used to find relations between required properties of annular plate and radial displacements of annular plate characteristic points.
