Abstract

The paper presents static analysis results of functionally graded material (FGM) cylindrical shells under concentrated load by an analytical approach. The basic equations are formulated based on a higher-order shear strain theory, taking into account the effects of transverse shear strain and stress. The one-dimensional material distribution in the thickness direction follows Voigt’s power law. In this article influences of several geometric parameters and material distribution coefficients on the stress state of FGM cylindrical shells are considered. Based on the analysis results at the clamped boundary zone, the local load concentration is found, and the transverse normal stress is demonstrated to be considerable at this zone.
