rdfs:comment	Un problema termomecànic és un problema mixt en què existeixen transmissió de calor entre sòlids sotmesos a tensió on els processos de deformació i dilatació tèrmica s'afecten mútuament. Usualment aquests problemes es plantegen com un sistema d'equacions diferencials derivades parcials. Aquests sistemes resulten complexos i actualment és freqüent resoldre'ls numèricament mitjançant el mètode dels elements finits i uns altres similars.

(es) L'analyse thermomécanique ou ATM (en anglais : thermomechanical analysis, TMA) est une technique d'analyse thermique. L'analyse thermique est une série de techniques qui mesure les propriétés physiques ou chimiques d'un matériau en fonction de la température, du temps et de l'atmosphère. (fr) Thermomechanical analysis (TMA) is a technique used in thermal analysis, a branch of materials science which studies the properties of materials as they change with temperature. Thermomechanical analysis is a subdiscipline of the thermomechanometry (TM) technique. (en) Thermo-mechanische analyse (TMA) is een thermische analysemethode waarbij men de afmeting van een monster meet tijdens verhitting. Het principe is eenvoudig. Het monster wordt gelegd op een klein plateautje gemaakt van een vuurvast en inert materiaal, bijvoorbeeld kwarts of aluminiumoxide. Er wordt een sonde opgezet en een oven wordt om het plateautje omhooggebracht. Een thermokoppel vlak naast het monster meet de temperatuur. De positie van de sonde wordt gemeten in afhankelijkheid van de temperatuur in de oven. (nl) Der Ausdruck Thermomechanische Analyse ist der Oberbegriff für die Messung von Dimensionsänderungen und Deformationen einer Probe, welche einem Temperaturprogramm unterworfen ist. Es handelt sich dabei um ein Verfahren der Thermoanalytik. In der TMA im engeren Sinn des Wortes wird die Deformation unter mechanischer Beanspruchung gemessen. In der dilatometrischen Betriebsart werden Dimensionsänderungen möglichst ohne Belastung der Probe erfasst.Abhängig von der Betriebsart erlaubt die TMA die Bestimmung von: (de) L'analisi termomeccanica (TMA, dall'inglese thermomechanical analysis) è un metodo di analisi termica in cui vengono misurati i cambiamenti dimensionali lineari o volumetrici in funzione della temperatura. Viene realizzata sottoponendo a sforzo il materiale oggetto di studio tramite l'applicazione di un carico statico. Insieme all'analisi meccanica dinamica (MDA), l'analisi termomeccanica rappresenta uno dei principali metodi termomeccanici di analisi. Quando lo sforzo applicato è nullo, la tecnica viene definita termodilatometria. (it)
