The Dependence of the Characteristics of the Dispersion Curves on the Orientation Angle of the CARALL Structures

EasyChair Preprint no. 9510

Abstract

This paper aims to provide a parametric analysis of the effect of fiber orientation angle on elastic wave dispersion relations in the instance of the CARALL composite. The material under consideration has 14 layers. Aluminum alloy and carbon/epoxy resin fibers are used to create the layers. The overall configuration of the CARALL composite is considered to be [Al, θ5, Al]s, and the angle is the parameter whose values are taken in the range [0°, 90°]. The stiffness matrix approach is used to determine the dispersion curves. In addition, the computer program "Dispersion calculator" is utilized. The shift in phase velocity of the basic symmetric mode and the horizontal shear mode is mostly noticed due to differences in the fiber orientation angle. The other modes' sensitivity to the angle is negligible

Keyphrases: CARALL, dispersion curve, Lamb wave
