The main idea of the course is to highlight the importance of fatigue problems and to qualify the participants to identify, evaluate and prevent fatigue motivated defects. Therefore, a training on two consecutive days will present the full range of fatigue analysis by presenting the theory and by practical experiments.
The course will concentrate on typical construction metals like steel or aluminium. The theoretical part of the course includes the background of fatigue cracks from the viewpoint of material science, the methods for a useful load analysis, the strength analysis using guidelines (‘FKM Guideline for Analytical Strength Assessment of Components in Mechanical Engineering’), the design of experiments and the estimation of remaining lifetime.In the practical part of the course the participants will learn how to measure loads using the example of a bicycle, how to classify the loads and finally how to use the data to perform an analytical, numerical or experimental fatigue analysis. Experimental testing methods will be presented by small, portable test rigs (rotating bending test of a shaft, pneumatic test rig of a handlebar), and by a visit of the fatigue test field of the institute of machine elements, design and manufacturing.
The training will be a balanced mixture of active periods with experiments and practical use-cases and passive periods where the lectures present the theory. The course will be subdivided in several thematic blocks. Each block will consist of a presentation of the theory, the methods and the workflow how to handle in practical applications. Furthermore, the participants will perform experiments, handmade analysis or learn how to handle a computer software to train the content of the block.
The following contents will be part of the course:

Objectives and outcomes
The target group of the course are designers, maintenance engineers and researchers. Participants from all kind of mechanical industry or research institutions are welcome. As pre-required knowledge the participants should be familiar with the basics in material behaviour and mechanical stress analysis.
M.Sc. Timo Roth studied from 2012 till 2017 mechanical engineering at Darmstadt University of Applied Science and Clausthal University of Technology. The focus of his study was in general mechanicalengineering (for example: welded connections, structural durability, engineering design, drive technology, simulation methods, measuring technology). After his graduation he worked two years asproject engineer at IME Aachen GmbH (a spin-off from the RWTH Aachen University) for fatigue strength and engineering design. He worked in many projects (experimental and simulative) with the focus onstructural durability. Excerpt of processed projects: Optimization of bolted joints for roller bearings of construction machinery, experimental investigation of shaft couplings, optimization of gearwheels ofmining machinery and combustion engines, investigations on (high speed) shaft-hub connections, endurance tests on frames, measurement of bearing forces under working conditions and lifetime calculation of the bearings, overload and endurance tests on drive trains. Since 2020 he is working as researcher at the Institute for Machine Elements, Engineering Design and Manufacturing at Technical University Bergakademie Freiberg. There, he gained experience in teaching of students with different backgrounds (course of study) and nationalities. He also supervised experimental and simulative projects with the focus on mechanical strength.
