Excerpt from Untersuchungen Uber den Einfluss der Art und des
Wechsels der Belastung auf die Elastischen und Bleibenden
Formanderungen Wenn es sich um Bestimmung der Zug und
Druckelastizitat fur irgend ein Material handelt, ist es wohl heute
noch allgemein ublich, fur Zug und fur Druck verschiedene Korper
und Korperformen zu verwenden. Dieses Verfahren reicht fur die
meisten praktischen Zwecke aus. Sobald man aber genaueren
Aufschluss uber das gegenseitige Verhaltnis der beiden
Elastizitaten, sei es absolut genommen oder wie im vorliegenden
Falle unter einem bestimmten Gesichtspunkte, erhalten will, konnen
nur solche Versuche auf vollen wissenschaftlichen Wert Anspruch
erheben, welche an dem gleichen Versuchskorper durch gefuhrt sind.

Angesichts del' ausserordentlichen Bedeutung, die die Chromgerbung
auch in Deutschland heute schon erlangt hat, muss es besonders
aufi'allend erscheinen, dass es noch kein Specialwerk tiber
Chromgerbung giebt, und gleichzeitig dtirfte das Fehlen eines
solchen Buches von den Fachleuten als ein grosser Mangel empfunden
worden sein, ebenso, wie er sich mil' selbst bei meiner, wenn auch
nul' theoretischen Beschaf- tigung mit del' Chromgerbung recht
haufig ftihlbar gemacht hat. In del' vorliegenden Arbeit ist nun
versucht worden, diese Lticke einigermassen auszuftillen. Es
handelt sich dabei nicht urn die Ergebnisse eigener Forschungen und
Versuche, sondern urn eine moglichst voll- standige und
tibersichtliche Zusammenstellung dessen, was bis- her tiber die
Chromgerbung verofi'entlicht und an Erfahrungen gesammelt worden
ist. Del' Fachmann wird also kaum wesent- lich N eues in den
folgenden Blattern finden; trotzdem dtirfte es auch ihm willkommen
sein, das bisher in der Fachpresse und Litteratur, sowie in
zahlreichen Patentschriften des In- und Auslandes verstreute
Material hier vereinigt zu finden. Von einer Sichtung des Materials
wurde dem vorstehend an- gegebenen Zwecke des Buches entsprechend
Abstand ge- nommen, abgesehen davon, dass eine solche Sichtung nul'
auf Grund eingehender Versuche hatte erfolgen konnen, deren
Ausftihrung mir nicht moglich war. In Uebereinstimmung damit wurden
auch die einschlagigen Patente des Auslandes trotz ihres oft mehr
als zweifelhaften Werthes und ungeachtet del' durch ihl'e
Wiedel'gabe veranlassten Wiederholungen ohne Dntel'schied
aufgenommen. Massgebend war lediglich del' Vorwort.
For courses in machine shop, machine tool technology, machining
processes/manufacturing processes technology, industrial
technology, industrial mechanics, and industrial engineering at the
undergraduate level. The all-in-one solution for teaching
machining, BPR, GD&T, and CNC courses Machine Tool Practices
provides clear, practical, and richly illustrated treatment of
machine tool technology and prepares students for NIMS
certification. Vast in breadth and depth, this is the definitive
text for training computer numerical controllers, conventional
machine operators, general machinists, and tool and tie makers. The
11th edition includes dramatically expanded content and supplements
on blueprint reading, GD&T, and CNC, giving it the potential to
be the sole source of material for courses on these topics, while
saving students the expense of two extra texts.
An increasingly important feature across the technical textile
industry is to produce textiles faster and to have more effective
new product development (NPD). New product development in textiles:
Innovation and production not only provides a fascinating overview
of how products are launched, but is also a source of practical
guidance for developing textile products successfully. Part one
provides a general overview of innovation and textile product
development that introduces the reader to the principles of
developing and defining new products. Part two goes on to discuss a
collection of international studies from across the textile
industry. Chapters describe actual new product development
projects, identifying the problems that were faced and what can be
learnt from these projects, such as customer co-creation and
methods for reducing the risk in NPD. Topics range from technical
textiles and apparel to the end uses of textiles used within the
automotive and packaging industries. With its distinguished editor
and international team of expert contributors New product
development in textiles: Innovation and production is an essential
guide for academics and textile development professionals
worldwide, in sectors ranging from design, production and marketing
through to management.
Accelerated Testing and Validation Methods is a cross-disciplinary
guide that describes testing and validation tools and techniques
throughout the product development process. Alex Porter not only
focuses on what information is needed but also on what tools can
produce the information in a timely manner. From the information
provided, engineers and managers can determine what data is needed
from a test and validation program and then how to select the best,
most effective methods for obtaining the data.
This book integrates testing and validation methods with a business
perspective so readers can understand when, where, and how such
methods can be economically justified. Testing and validation is
about generating key information at the correct time so that sound
business and engineering decisions can be made. Rather than simply
describing various testing and validation techniques, the author
offers readers guidance on how to select the best tools for a
particular need, explains the appropriateness of different
techniques to various situations and shows how to deploy them to
ensure the desired information is accurately gathered.
* Emphasizes developing a strategy for testing and validation
* Companion website includes example spreadsheets, program source
code, case studies, video clips and much more
* Teaches how to design a testing and validation program that
deliver information in a timely and cost-effective manner
