New general decay results for a viscoelastic plate equation with a logarithmic nonlinearity

Abstract

In this paper, we investigate the stability of the solutions of a viscoelastic plate equation with a logarithmic nonlinearity. We assume that the relaxation function g satisfies the minimal condition g (t) ≤-ξ (t)G(g(t)), where ξ and G satisfy some properties. With this very general assumption on the behavior of g, we establish explicit and general energy decay results from which we can recover the exponential and polynomial rates when G(s) = s p and p covers the full admissible range [1, 2). Our new results substantially improve and generalize several earlier related results in the literature such as Gorka (

On the blow-up of the Cauchy problem of higher-order nonlinear viscoelastic wave equation

“…Under suitable conditions on relaxation function g and the positive initial energy as well as non-positive initial energy, it is proved that the solution blows up in the finite time. Recently, Algarabli [1], investigated the stability of the solutions of a viscoelastic plate equation with a logarithmic nonlinearity of the form…”

Blow-Up for a Stochastic Viscoelastic Lamé Equation with Logarithmic Nonlinearity

“…These specific applications in physics and other fields attract a lot of mathematical scientists to work with such problems. In the deterministic case, Al-Gharabli [11] investigated the stability of the solution of a viscoelastic plate equation with a logarithmic nonlinearity source term for the following problem:…”
