TL;DR: In this article, the basic mechanisms of these phenomena are discussed and the basic concepts can be found in a number of good text books and it seems worthwile to recall them in a short comprehensive paper.

TL;DR: The case went to court for negligent homicide after a preliminary investigation had been performed as mentioned in this paper and the defendants engaged a number of experts to investigate the different technical aspects of the accident for their defence and the result of the hearing was in the opinion of most experts, that the accident could not be explained by the results of the investigations performed.

TL;DR: In this paper, the problem of estimating the S-N field based on samples with different lengths and testing the hypothesis of length independence of fatigue lifetimes was dealt with and the analysis showed that in the first case the length independence assumption cannot be accepted while for the second case length independence seems to be a reasonable assumption.

TL;DR: In this paper, the fatigue strength for various laminates of a carbon fiber reinforced thermoplastic material (AS4/APC-2) was investigated experimentally up to 109 cycles and a fatigue design procedure was developed, which allows predicting the fatigue life of a typical structural detail under bending loads.

TL;DR: In this article, a new model of crack growth is presented, which physically attributes this region to the formation and subsequent fracture of a crack tip oxide layer, which is measured with X-ray photon electron spectroscopy.
