The investigation focuses on the fatigue mechanisms and crack initiation of nickel, aluminum, and copper in the Very High Cycle Fatigue regime, utilizing a custom-built resonant fatigue setup. The study reveals that the resonant frequency of samples changes with increasing cycle numbers, indicating fatigue damage. Notable mechanisms observed include slip band formation, cyclic hardening, and the formation of vacancies and oxidation, which are identified as early indicators of fatigue.
This is an important book. The topic is important, and Dr. Straub approaches it with a new approach. In fact, one could say that the book’s importance stems from its lack of disciplinary focus, relying instead on a holistic understanding of the phenomenon. Too often, academic research is pursued within a narrowly defined academic “field”, necessarily blinding researchers to realities whose essence is inter-disciplinary. This is typically the case with research on Mergers & Acquisitions, making most of the “findings” relatively unimportant for practice. Yet M& A are a crucial part of business development. It is evident that companies’ long-term success is at least partially dependent on their strategic actions. And these are often shaped in practice by merger and acquisition activity. Thus phenomena as varied as globalization, value-chain optimization, or product diversification are often implemented as M& A operations. In no few cases, M& A activity constitutes the company’s strategy. If, as noted above, strategic moves do have an impact on lo- term success, it follows that M& A activities are at the core of many business successes… and failures. As such, they play an important role in the development of the whole society: wealth is created (or destroyed) mostly by companies. Perhaps the most remarkable aspect of the phenomenon is its very high failure rate.
