Depending on the amount of data to process, file generation may take longer.

If it takes too long to generate, you can limit the data by, for example, reducing the range of years.

EN Materials exhibiting a rate-dependency in a mechanical loading regime enclose a variety of deformation mechanisms depending on their microstructure. This holds true for material classes from plastics to metals and is increasingly important for high-performance structural components. Material models covering viscoplastic deformation with hardening effects for metals have been widely studied in the last decades. The deformation mechanisms contribute to stored energy and dissipation and are reflected in the balance of energy. The current temperature measurement techniques give new opportunities to exploit an accurate temperature field to prove and validate material models. Especially, contact-free thermography with a small resolution range up to 1mK is becoming more popular in mechanical testing set-ups. The paper examines a thermomechanical approach and an experimental concept for a material law verification and validation for self-heating in small temperature ranges. The focus lies on loading regimes incorporating holding times and the unloading path. An advanced thermographic measurement method is applied. It is pointed out that the thermomechanical approach is valuable and informative to assess the observed deformation processes and to describe the material behaviour with a thermodynamically valid parameter set.
