Continuum Scale Simulation of Engineering Materials

Die Simulation von Materialien gehört zu den interessantesten neuen Forschungsgebieten der Ingenieurwissenschaften. Dieser Band spricht alle wichtigen Aspekte des Themas an, von den mathematischen Grundlagen der Simulation über Anwendungen beim Design von Mikrostrukturen bis zur computergestützten Werkstoffauswahl und -entwicklung. Doktoranden und Praktiker aus Materialwissenschaft und Technik lernen, aus den existierenden Simulationsmethoden den für ihr Problem am besten geeigneten Ansatz auszuwählen.

This book fills a gap by presenting our current knowledge and understanding of continuum-based concepts behind computational methods used for microstructure and process simulation of engineering materials above the atomic scale. The volume provides an excellent overview on the different methods, comparing the different methods in terms of their respective particular weaknesses and advantages. This trains readers to identify appropriate approaches to the new challenges that emerge every day in this exciting domain. Divided into three main parts, the first is a basic overview covering fundamental key methods in the field of continuum scale materials simulation. The second one then goes on to look at applications of these methods to the prediction of microstructures, dealing with explicit simulation examples, while the third part discusses example applications in the field of process simulation. By presenting a spectrum of different computational approaches to materials, the book aims to initiate the development of corresponding virtual laboratories in the industry in which these methods are exploited. As such, it addresses graduates and undergraduates, lecturers, materials scientists and engineers, physicists, biologists, chemists, mathematicians, and mechanical engineers.
