In the present work, we investigate stochastic third grade fluids equations in a d-dimensional setting, for d = 2, 3. More precisely, on a bounded and simply connected domain D of ℝd, d = 2,3, with a sufficiently regular boundary ∂ D, we consider incompressible third grade fluid equations perturbed by a multiplicative Wiener noise. Supplementing our equations by Dirichlet boundary conditions and taking initial data in the Sobolev space H1(D), we establish the existence of global stochastic weak solutions by performing a strategy based on the conjugation of stochastic compactness criteria and monotonicity techniques. Furthermore, we study the asymptotic behaviour of these solutions, as t → ∞.
