Modeling Steel Deformation in the Semi-Solid State

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.

Aceasta carte ofera o abordare unica a modelarii integrate a proceselor la temperaturi ridicate, menita sa serveasca drept ajutor de proiectare pentru noile tehnologii de prelucrare a metalelor. A doua editie a fost extinsa substantial pentru a include continut nou, cum ar fi: un nou algoritm si rezultatele testelor de vizualizare stereoscopica 3D; noi proceduri de programare pentru modelare; validarea simularii pe computer folosind rezultate experimentale; un model multi-scala de crestere a cerealelor; o metodologie conceptuala care dezvolta diagrame CCT (transformare continua la racire) si multe alte exemple de validare a simularilor numerice. Modelele prezentate sunt aplicate in teste cuprinzatoare pentru a rezolva problemele legate de deformarea la inalta temperatura a otelului.
