Devices based on disordered semiconductors have wide applications. It is difficult to imagine modern life without printers and copiers, LCD monitors and TVs, optical disks, economical solar cells, and many other devices based on disordered semiconductors. However, nowadays books that discuss disordered (amorphous, nanocrystalline, microcrystalline) semiconductors focus, as a rule, on either physics of materials or physics of devices that are based on these materials. This book connects characteristic features of the atomic and electronic structures of disordered semiconductors and the device design process on the basis of these materials.

Everything engineers need to know about mechanical vibration and shock...in one authoritative reference work!

This fully updated and revised 3rd edition addresses the entire field of mechanical vibration and shock as one of the most important types of load and stress applied to structures, machines and components in the real world. Examples include everything from the regular and predictable loads applied to turbines, motors or helicopters by the spinning of their constituent parts to the ability of buildings to withstand damage from wind loads or explosions, and the need for cars to maintain structural integrity in the event of a crash. There are detailed examinations of underlying theory, models developed for specific applications, performance of materials under test conditions and in real-world settings, and case studies and discussions of how the relationships between these affect design for actual products.

Fatigue damage in a system with one degree of freedom is one of the two criteria applied when comparing the severity of vibratory environments. The same criterion is also used for a specification representing the effects produced by the set of vibrations imposed in a real environment. In this volume, which is devoted to the calculation of fatigue damage, Christian Lalanne explores the hypotheses adopted to describe the behavior of material affected by fatigue and the laws of fatigue accumulation.

The vast majority of vibrations encountered in the real environmentare random in nature. Such vibrations are intrinsically complicatedand this volume describes the process that enables us to simplifythe required analysis, along with the analysis of the signal in thefrequency domain.
The power spectrum density is also defined, together with therequisite precautions to be taken in its calculations as well asthe processes (windowing, overlapping) necessary to obtain improvedresults.

This volume considers the shock response spectrum, its variousdefinitions, properties and the assumptions involved in itscalculation. In developing the practical application of theseconcepts, the forms of shock most often used with test facilitiesare presented together with their characteristics and indicationsof how to establish test configurations comparable with those inthe real, measured environment. This is followed by a demonstrationof how to meet these specifications using standard laboratoryequipment – shock machines, electrodynamic exciters driven bya time signal or a response spectrum – with a discussion onthe limitations, advantages and disadvantages of each method.
