Preface
This book features state-of-the-art contributions in mathematical,
experimental and numerical simulations in engineering sciences. The
contributions in this book, which comprise twelve chapters, are
organized in six sections spanning mechanical, aerospace, electrical,
electronic, computer, materials, geotechnical and chemical
engineering.
Topics include metal micro-forming, compressible reactive flows, radio
frequency circuits, barrier infrared detectors, fiber Bragg and long-
period fiber gratings, semiconductor modelling, many-core architecture
computers, laser processing of materials, alloy phase decomposition,
nanofluids, geo-materials and rheo-kinetics. Contributors are from
Europe, China, Mexico, Malaysia and Iran.
The chapters feature many sophisticated approaches including Monte
Carlo simulation, FLUENT and ABAQUS computational modelling,
discrete element modelling and partitioned frequency-time methods.
The book will be of interest to researchers and also consultants
engaged in many areas of engineering simulation.

Abstract
Microforming is a technology of very small metal elements production, which are
required as a parts for many industrial products resulting from microtechnology. This
chapter gives a review of the state-of-the-art microforming of metals and its numeri‐
cal simulations. Phenomena occurring in the miniaturization of microbulk-forming
technologies are described. The main problems in microforming are size effects, which
have physical and structural sources and directly affect the material flow mechanics in
microscale. Size effects must be taken into account in all areas of the forming process
chain, demanding new solutions, especially in workpiece structure and die surface
numerical modeling.
Keywords: microforming, size effects, numerical simulation
1. Introduction
Trend of miniaturization of everyday devices increases industry demand for efficient produc‐
tion of miniature parts. Machining production technologies of small-dimension elements by
turning, milling, and polishing are well known for a long time. However, these methods are not
efficient enough for the great demand for small and handy devices. This makes engineers to
search for new methods of microelements manufacturing or to adapt traditional ones for the
requirements of miniaturization.
Microforming is an adopted technology of production of small parts by metal forming. This
process is characterized by good productivity, high dimensions accuracy, proper surface
smoothness, high material usage, and good mechanical properties of manufactured items,
