Özet

This paper is devoted to the study of long-time dynamics of a Cauchy problem related to extensible beam models with dissipative effects coming from the nonlocal Balakrishnan-Taylor and the localized weak damping terms in R-n. Our first main result features a new unique continuation property for models associated with extensible beams. Then, applying such a property and with the fundamental aid of the nonlocal Balakrishnan-Taylor damping term, we state and prove our second main result dealing with the existence, characterization and regularity of a compact global attractor for the corresponding nonlinear dynamical system.
