Abstract Background: A theoretical study was performed of mode II delamination in a multilayered functionally graded beam configuration with considering the material non-linearity.

The J-integral closed form non-li…
Abstract Background: In rubber elastic models it is generally assumed that the bulk modulus is infinite, resulting in a material that does not change its volume and a pressure that cannot be evaluated from the material model. Methods: We have developed a general procedure that incorporates a finite bulk modulus. Using the developed framework accurate results can be obtained without the need…

Abstract Background: Impedance pump is a simple valveless pumping mechanism, which transports fluid through the mismatch of impedance in the system. Mismatch in impedance occurs when an asymmetrical periodic excitation is exerted on the elastic tube. Periodic asymmetrical excitation will then produce a unidirectional flow. Considering a multi-stage system with a single and constant power so…

All mechanical equipment in motion generates a vibration profile, or signature, that reflects its operating condition. This is true regardless of speed or whether the mode of operation is rotation, reciprocation, or linear motion. Vibration analysis is applicable to all mechanical equipment, although a common—yet invalid—assumption is that it is limited to simple rotating machinery with run…
This book is written as simply as possible, in plain English, by a Scottish engineer/trainer. It initially explains what each method or individual topic is about and then goes on to list the steps you should follow to implement what you have just learned. Then you learn the next bit and follow the steps—it encourages the readers to adapt some parts and tailor them to their own needs. This app…
The motor car is over one hundred years old. The suspension is an important part of its design, and there have been many research papers and several books on the topic. However, suspension analysis and design are so complex and bring together so many fields of study that they seem inexhaustible. Certainly, the number of different suspension designs that have been used over the years is consi…
The profitability of any industry, in any technological sector-power, process, manufacturing, mineral extraction, transport, communication-will be profoundly influenced by the reliability and performance of the plant which it uses. It is therefore vital that all possible measures are taken to maximize the productivity in use, and to minimize the maintenance costs and the downtime, of that plant…
To get the most out of this book, I recommend reading it in three passes. On your first pass, flip through the entire book and look at all of the chapters, examining the book’s organization and the figures. Get acquainted with the style and flow. On the second pass, go through the book chapter by chapter. At the start of each chapter, conduct another quick review of the chapter. During this r…
What a long story welding is! Seeing the light of day at the end of the 19th century in the mind of scientists, it passed quickly into the hands of technicians, first of all with the oxyacetylene technique, then with arc welding and resistance welding techniques. Other processes (we will not quote them all in this introduction) then followed and the 20th century ended with laser welding whi…

Systems Engineering has long been established in the fields of avionics and software development. In the automotive sector too, we are witnessing an increasing number of systems engineering approaches. Nonetheless, a distinct profile has still to be developed that clearly defines its limits and interfaces with other development and research areas and gives a specific identity to automotive …
One of the things that I fi nd most interesting about automotive technology is how it advances and changes. It is also interesting that ideas from many years ago often return to favour. In this book I have therefore concentrated on core technologies, in other words how the technology works, rather than giving too many examples from specifi c vehicles. However, I have included some examples of F…
In the beginning, say 115 years ago, a book on vehicle electrics would have been very small. A book on vehicle electronics would have been even smaller! As we continue our drive into the new millennium, the subject of vehicle electrics is becoming ever larger. Despite the book likewise growing larger, some aspects of this topic have inevitably had to be glossed over, or left out. However, the b…
The book has grown! But then it was always going to, because the complexity of automotive systems has grown and the associated diagnostic skills must follow. The main change for this edition is that I have included two completely new chapters. The first is all about on-board diagnostics (OBD) and the second covers oscilloscope diagnostics in some detail. Both of these subjects are very relev…

The book is divided into 11 chapters, in which the principles are first applied to simple, then to more complicated situations. In a general sense, each principle is applied first to a particle, then a rigid body subjected to a coplanar system of forces, and finally to three-dimensional force systems acting on a rigid body. Chapter 1 begins with an introduction to mechanics and a discussi…
