内容説明

Two developments are transforming the ways processes in materials are modelled. Developments in computing stem partly from faster machines with enhanced memory, partly form new strategies and general-purpose codes and partly from new graphics to help both expert and non-specialist. Developments in science encompass scale, sophistication and complexity. Parameter-free calculations are now common; many issues of excited states, high temperatures, interfaces and grain structure evolution are resolved. Atomistic studies at the microscopic extreme are linked to macroscopic approaches via the mesoscopic scale, at which texture matters. This transformation is changing ambitions in the way that modelling is exploited. The range of systems has grown as science takes up the challenges of technology; theory , once a simple framework, is proving an important means to design and optimize materials and their applications.
