Martin Bartelt, Dr.-Ing.

Head of Test Lab

Responsible for the organization as well as safe and efficient operation of the test lab, and for technical and logistical support of research and teaching experiments. This includes, in particular, the coordination of users and resources, compliance with safety and legal regulations, the maintenance of facilities and infrastructure, and the further development of the hall in accordance with the requirements of research and teaching.

Consulting, development and implementation of research projects from industry

Research at TU Braunschweig benefits from the broad spectrum of knowledge of over 120 institutes and access to internal structures from professors to first-semester students.

Fatigue and Fatiguelimits in the VHCF-range of thin fiber reinforced plastics (VHCF-2)

Determination of fatigue influences and limits

• Influences: material, layer thickness, stress ratio, type of load
• Limits: Crack prediction, crack growth limit, delamination growth limit
