Abstract
In this paper, a perturbation approach is used to calculate the asymptotic growth rate of stochastically coupled two-degree-of-freedom nonlinear stochastics systems. The noise is assumed to be white and of small intensity in order to calculate the explicit asymptotic formulas for the maximum Lyapunov exponent. The almost-sure sample stability or instability of the four-dimensional stochastic system depends on the sign of the maximum Lyapunov exponent.
