The dynamic behaviors of structures in principle of a non-conservative system, such as a submerged thin shell structures under hydrostatics type load in the circulatory system, may assume various nature phenomena. Especially, disturbance forces of various types, which are omnipresent in a marine environment, may occur complexity and unstable for dynamic behaviors of shell structures in non-conservative system. This paper deals with characterizing the dynamic stability of a thin shell subjected to follower forces with small disturbances using Lyapunov exponent, in order to clarify the structural mechanisms of dynamic motions and critical threshold. The dynamic behavior a partial spherical shell is herein investigated to analysis unstable state through non-periodic motion in accordance with two scenarios as "self-organization type" and "self-assembly type".
