Static and Dynamic Analysis of Thermoviscoelastoplastic Fiber-Reinforced Composite Shells in Missile Structures.

摘要

It has been postulated that anisotropic structures such as the fiber composites should be governed by kinematic hardening. The final phase of this research therefore,was undertaken to investigate the feasibility of incorporating the changes of degrees of anisotropy during the post-yielding deformations. The present report describes the development of kinematic plastic function theory,the first of its kind ever used for the analysis of fiber composites. The method requires a considerable amount of computing time,but upon careful reprogramming,it is believed to be a powerful tool in the analysis of missile structures.
