A heat transfer analysis was performed to evaluate the temperature distribution on the specimen during the cooling under an impinging air jet; temperature measurements performed with an infrared pyrometer on the cooled samples show good agreement with the evaluated data. These results were then integrated in a structural mechanic model as thermal load. The COMSOL Multiphysics? Thermal-Structural interaction model allowed to determine the dependence of the stress on the temperature fields}, url = {http://eprints.imtlucca.it/3821/} }
