摘要

Bi-stable composite cylindrical shells have attracted many attentions due to their lightness, simple structure, high packaging efficiency, high specific strength and stiffness. However, the anti-symmetric cylindrical shell is susceptible to the effect of ambient temperature and humidity. In this paper, an analytical model of shell structure considering hydrothermal effect was built, and its strain energy expressions were derived. Based on the minimum energy principle, the effects of moist and heat on the bi-stability of cylindrical shell structure were analyzed. In addition, the finite element model of the anti-symmetric cylindrical shell was established to simulate its stable configurations. This study could provide reference for the practical application of bi-stable structure.
