The influence of frequency is clearly recognizable in the cyclic deformation curves of load increase tests (LIT) in the form of a shift of the first material response to higher stress amplitudes (220 MPa for 80 Hz and 240 MPa for 260 Hz). This first material response can also be used to estimate the fatigue strength of the material. The increase

Pre-Study Internship
Practical experience is one of the direct admission requirements for the degree course. It is usually acquired during the basic internship.
By being involved in professional practice, the intern learns work techniques and work processes from their own experience and thus gains an understanding and awareness of the problems i
