Thermomechanical analysis principle
WebbOne of the most widely used technique to measure dimensional changes of solid or liquid materials as a function of temperature, time and applied force is the thermomechanical analysis (TMA). This method is often used to measure a material's coefficient of thermal expansion (CTE), glass transition temperature ( Tg ), and (compression) modulus. WebbPrinciple: The thermomechanical analysis (TMA) allows you to measure quickly and easily the change of dimension of the sample (expansion, shrinkage, movement, etc.) as a …

Simultaneous Thermal Analysis (STA) generally refers to the simultaneous application of Thermogravimetry (TGA) and Differential Scanning Calorimetry (DSC) to one and the same sample in a single instrument. WebbSamples of three common commercial gutta-percha endodontic filling points (Hygienic, Mynol, and Maillefer Pink) and a sample of natural gutta-percha were submitted to thermomechanical analysis under pressures ranging from 0.01 to 0.2 N. Samples of Mynol and Maillefer filling points were thermally tr …
Webb29 juli 2024 · To determine the thermal expansion coefficient, two physical quantities (displacement and temperature) must be measured on a sample that is undergoing a thermal cycle. Three of the main techniques used for CTE measurement are dilatometry, interferometry, and thermomechanical analysis. Optical imaging can also be used at … WebbA technique in which the temperature of the sample unit, formed by a sample and reference material, is varied in a specified program, and the temperature difference …
