Axisymmetric Analysis of the Cylindrically Orthotropic Disk of Variable Fiber Orientation,

Abstract

Injection molding of axisymmetric bodies with fiber-reinforced molding compounds results in cylindrically orthotropic components in which the fiber orientation varies with radial position. Consequently, development of analysis techniques for determining the effect of material property variability on the response of these components is of great importance. In the present study, a numerical integration scheme for the analysis of cylindrically orthotropic annular disks with variable elastic constants is presented. The influence of material property variations, temperature changes and centrifugal forces on the response of an annular disk subjected to internal and external pressure or displacement boundary condition is included in the analysis. Correlation of numerical integration results with analytical and finite-element solutions is excellent. (AN)
