Abstract

An impact response analysis for a transversely isotropic circular cylindrical shell is carried out using the method of eigenfunction expansion based on the theory of 3D elastodynamics. The circular cylindrical shell is simply supported at its end surfaces, and a partially distributed uniform load is suddenly applied to its outer surface. Numerical results for stress and displacement responses at some locations of interest are shown graphically, and then the influences of anisotropy on the impact response are discussed. The higher stress response will be occurred in the direction with higher longitudinal elastic modulus. 1 Introduction Circular cylindrical shells are widely used in aerospace, civil and many other engineering industries, and the corresponding
