Collapse loading and energy absorption of fiber-reinforced conical shells

Abstract

Background/PurposeAn analytical solution is presented to predict the mean axial collapse forces of fiber reinforced conical shells under thermal loading, in which the fibers wrapped orientation is arbitrary; MethodsAnalytical method and finite element simulate; ResultsThe influences of thermal loading, fibers wrapped orientations, geometrical eccentricity factor and proportionality coefficient on the axial collapse force of fiber reinforced conical shells are given. ConclusionThe collapse loading Pm of fiber-reinforced conical shells appears in the maximum value under different thermal environment when the fibers wrapped direction equals 45°. By optimizing the wrapping orientation of fiber layers, the capability of energy absorption of fiber-reinforced conical shells can be enhanced.
