General decay for weak viscoelastic Kirchhoff plate equations with delay boundary conditions
Boundary Value Problems, 2017 We consider a weak viscoelastic Kirchhoff plate model with time-varying delay in the boundary. By using a suitable energy and Lyapunov function, we obtain a decay rate for the energy, which depends on the behavior of g and α.

AIMS MathematicsIn this paper, we investigate a von Karman plate system with general type of relaxation functions on the boundary. We derive the general decay rate result without requiring the assumption that the initial value $ w_0 \equiv 0 $ on the boundary, using the

General decay in a Timoshenko-type system with thermoelasticity with second sound
Advances in Nonlinear Analysis, 2015 In this article, we consider a vibrating nonlinear Timoshenko system with thermoelasticity with second sound. We discuss the well-posedness and the regularity of solutions using the semi-group theory.

On a Laminated Timoshenko Beam with Nonlinear Structural Damping
Mathematical and Computational Applications, 2020 In the present work, we study a one-dimensional laminated Timoshenko beam with a single nonlinear structural damping due to interfacial slip. We use the multiplier method and some properties of convex functions to establish an explicit and general decay ...

Temporal decay bounds in generalized heat conduction
Journal of Mathematical Analysis and Applications, 2004 The authors consider the generalized Maxwell-Cattaneo model for heat conduction in \(\mathbb R^N\) \((N = 2, 3)\). By using a suitable change of variable for the temperature \(T\) and exploiting the multiplier method, they establish an exponential decay bounds for \(T\), as well as its first partial derivatives, in the \(L_2(\Omega)\) norm.
