Abstract: A method for thermomechanical testing of a test specimen, characterized in that the test specimen is subjected to a high-speed thermal mass flow and a force acting on the test specimen as a result of the exposure is continuously determined by a determination device and a force-time curve is determined therefrom. A test device for thermomechanical testing of a test specimen is also related.
