Static and Dynamic Analysis of Viscoelastoplastic Fiber Reinforced Composite Shells in Missile Structures

Abstract

A discussion is presented on theories, formulations, and computer programs for the analysis of shell structures in general and fiber reinforced rocket motor cases in particular. Arisymmetric isothermal deformations subjected to either static or dynamic loading are included in the present study. All possible material properties such as elastic, viscoelastic, elastoplastic, and viscoelastoplastic are explored. Analyses are carried out with the structure regarded either as a thin shell or as a thick shell. It was found that the thin shell theory is inadequate for yielding of many layers of fibers through the shell thickness. The finite element method is used in handling unusual geometry and boundary conditions and various modern numerical schemes are employed in domains of space and time.
