Modeling Steel Deformation in the Semi-Solid State (Advanced Structured Materials (47))

This book offers a unique approach to integrated high-temperature process modelling, intended to serve as a design aid for new metal processing technologies. The second edition has been substantially expanded to include new content such as: a new algorithm and test results of 3D stereoscopic visualization; new programming procedures for modelling; the validation of computer simulation using experimental results; a multiscale model of grain growth; a conceptual methodology developing “high-temperature” CCT (continuous cooling transformation) diagrams, and many more examples validating the numerical simulations. 

The models presented are applied in comprehensive tests in order to solve problems related to the high-temperature deformation of steel. The testing methods include both physical tests using specialist laboratory instruments, and advanced mathematical modelling: the Finite Element method (FE), Smoothed Particle Hydrodynamics method (SPH) and Mo

nte Carlo method (MC).This approach, which integrates the fields of physical and computer-based simulations, forms the basis for the described concept of integrated high-temperature process modelling, presented in detail in this book.

Dr Marcin Hojny is a researcher and lecturer at the AGH University of Science and Technology in Cracow, Poland, where he lectures on concurrent design systems as well as numerical methods and simulations. He is the author of the continuously developed DEFFEM simulation package as a development aid intended for use with modern Gleeble series research workstations. His scientific interests include the practical use of physical and computer simulations within the context of new technology development aids, mainly for the aviation and automotive industries. In particular, his work explores the modelling of processes and phenomena occurring at temperatures exceeding those seen in classic hot forming processing. He is the author of over 100 articles, including 16 from the Journal Citation Report (JCR) list, as well as two published books.
