In this article, we consider a von Karman equation with variable exponent nonlinearitiesw t t ( x , t ) +Δ 2 w ( x , t ) + | w t ( x , t ) | γ ( x ) − 2w t ( x , t ) = [ w ( x , t ) , F ( w ( x , t ) ) ] + | w ( x , t ) | p ( x ) − 2 w ( x , t ) in a bounded domain Ω ⊂ ℝ 2 . We firstly discuss an existence result of solutions by utilizing Faedo‐Galerkin approximation technique. Then, we undertake an investigation of asymptotic stability to the solutions by making use of the multiplier method.
