In the absense of any additional mechanical dissipations, the system is often not even strongly stable unless restricted to the rotationally symmetric case, etc. We present a well-posedness result for the linear problem under general mixed boundary conditions for the elastic and thermal parts. For the case of a clamped, thermally isolated plate, we show an exponential energy decay rate under a full damping for all elastic variables. Restricting the problem to the rotationally symmetric case, we further prove that a single frictional damping merely for the bending compoment is sufficient for exponential stability. To this end, we construct a Lyapunov functional incorporating the Bogovskii operator for irrotational vector fields which we discuss in the appendix.</dcterms:abstract> <dc:rights>deposit-license</dc:rights> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103605204-4002607-1"/> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/25341"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2013-12-13T08:33:38Z</dc:date> <dcterms:issued>2013</dcterms:issued> <dc:contributor>Pokojovy, Michael</dc:contributor> <dcterms:title>On Stability of Hyperbolic Thermoelastic Reissner-Mindlin-Timoshenko Plates</dcterms:title> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2013-12-13T08:33:38Z</dcterms:available> <dc:creator>Pokojovy, Michael</dc:creator> </rdf:Description> </rdf:RDF>
