This book is the first introduction/reference to the computer simulation of glass
materials, which are growing in their applications such as telephone technology, construction materials, aerospace materials and more.
Written by the leading experts and active practitioners from across the world, this book provides a comprehensive review of the fundamentals and practical applications of atomistic simulations of inorganic glasses. After providing a concise overview of both classical and first principles simulation methods, the second part of the book focuses on practical examples of the application of atomistic simulations in the research of different glass systems: silica, silicate, aluminosilicate, borate, chalcogenide and halide glasses. Up-to-date information will be provided on simulations (both classical and ab initio methods) of these glass systems, and current challenges facing these systems will be discussed. Students and researchers in the fields of materials science, particularly glass science and ceramic engineering, inorganic solid state chemistry, computational materials and materials modeling will benefit from this important new book.
