Abstract:International audienceThermoelastic stress analysis and quantitative calorimetry are full-field noncontact techniques widely used to study the thermomechanical behaviour of materials. The first one linearly relates the sum of the principal stresses to the temperature variation, and the second one can be used to measure the mechanical dissipation. However, brittle materials such as glass are a priori bad candidates for these techniques. Indeed, their low-temperature variations under loading lead to very noisy i… Show more
