Well-posedness and exponential stability of a dynamic frictionless contact problem with normal compliance and infinite memory
摘要
A model for dynamic frictionless contact between a viscoelastic body and foundation is considered. The viscoelastic constitutive law is assumed to be nonlinear and the contact is modelled with the normal compliance condition. We obtain the well-posedness using nonlinear semigroup theory arguments. Moreover, the exponential stability result of the solution is shown by using the energy method to produce a suitable Lyapunov function.
