The interdisciplinary field of materials technology is crucial for development of new materials, facing a huge spectrum of challenges in the area of natural resources, energy, new functionality, environmental impact, and so forth.

Computational modelling and simulation on quantum mechanics, molecular dynamics, and continuum mechanics levels play an ever increasing role in materials technology. Together with automatic computer optimization of different materials technology aspects, they form a framework for virtual design of new materials and processes. This framework is built on multiscale, multiphysics, and multiobjective components. New numerical methods and parallelization on large computers give this research field an additional acceleration. The virtual design avoids many expensive experiments and prototyping. In addition, completely new materials and production processes can be tested well before actual materials synthesis or production process construction.

The present special issue is dedicated to the contemporary efforts in the described field.
