Topic Description:
 

During plastic deformation of metallic materials, part of the applied mechanical energy is converted into heat, resulting in heating of the specimens. This thermomechanical effect can provide insight into the underlying inelastic processes and the dissipated energy. The ITM is currently developing a test rig consisting of a modern (biaxial) tensile testing machine with an optical strain sensor and a high performance thermographic camera to measure the temperature distribution. This setup will be complemented by an evaluation algorithm for processing the measured data.

The aim of the work is to validate the existing measurement setup and the evaluation algorithm in order to perform a quantitative determination of the heating of metallic samples during plastic deformation and to be able to estimate the measurement uncertainties.

What we offer:

- Access to a modern measurement setup with high quality equipment
- Supervision by an experienced team that has already carried out preliminary work in this field
- The opportunity to deepen your experimental and analytical skills in a current research topic

What you should bring:

- An interest in mechanics, materials science and thermodynamics
- Basic knowledge of measurement technology and data analysis (e.g. MATLAB or Python) is an advantage
- Motivation and enjoyment of experimental work
