intelligent materials, artificial intelligence, etc. are going to play a major role in
mechanical engineering. In the second article, G. K. Ananthasuresh exposes the
readers to exciting designs in micro-electro-mechanical systems (MEMS).
G. Chakraborty and Nikul Jani describe nonlinear dynamics of MEMS. A glimpse
of numerical techniques for studying the chatter has been provided by Chigbogu
Ozoegwu and Peter Eberhard; stability study of thin-walled milling process is taken
as an example.
It is envisaged that space elevators will replace (or supplement) rockets to
transport goods in the space. So far a space elevator has not been developed, but in
the next two–three decades, it may become a reality. In the fifth chapter,
Arun K. Misra and Stephen Cohen discuss the statics and dynamics of space
elevators. Gautam Biswas and Kirti Chandra Sahu have presented a brief survey on
free surface flows. They highlight that the numerical study of free surface flows will
find application in ink-jet printing, combustion, microfluidics, etc. Kiran Raj M. and
Suman Chakraborty discuss the hydrodynamics of deformable micro-channels.
With the discussion on bio-fluid mechanics, their article also reveals how the proper
study of micro-channels can revolutionize the medical field. The discussion on
application of microfluidics in the medical field is continued by Vijai Laxmi,
Siddhartha Tripathi, and Amit Agrawal in the eighth chapter; several examples of
lab-on-chip devices have been provided in this chapter.
Origami is an ancient Japanese art of folding the paper to produce
three-dimensional complex shapes. Derosh George and Marc J. Madou discuss how
this art can be used to fabricate MEMS. Finally, in the tenth chapter, Anish Roy,
Qiang Liu, U. S. Dixit, and Vadim V Silberschmidt provide a glimpse of the power
of simulation in manufacturing. With an example of machining simulation, it is
demonstrated how the manufacturing, traditionally an artistic activity, can be
scientifically studied and controlled. In the last chapter, Jyoti Mazumder takes us to
the exciting world of laser-aided manufacturing.
We hope that this book will provide sufficient exposure to the audience and will
also motivate researchers in the futuristic areas of mechanical engineering. It can
also be useful for technology managers and policy-makers. We welcome the
feedback from the readers.
