Abstract
In this article, we consider a nonlinear plate (or beam) Petrovsky equation with strong damping and source terms with variable exponents. By using the Banach contraction mapping principle we obtain local weak solutions, under suitable assumptions on the variable exponents p(.) and q(.). Then we show that the solution is global if \(p(.) \geq q(.)\). Also, we prove that a solution with negative initial energy and \(p(.)<q(.)\) blows up in finite time.
