Abstract
Continuum modeling approaches are well established in materials science
and engineering of metals. They enable the quantitative investigation
of diverse questions related to the improved understanding of mechanics
and microstructure evolution of various material classes. Applicable
to time and length scales relevant in manufacturing and service,
continuum modeling approaches are widely used to study engineering-related
phenomena such as recrystallization, strain localization, fracture
initiation, and phase transformations. However, focusing on individual
physical aspects hampers the wider routine use of continuum modeling
tools for many engineering applications. With the advent of multi-physics
modeling tools developed with the help of and parametrized by (sub-)micrometer-scale
simulations and experiments, a huge variety of applications such
as hot rolling, bake-hardening, and case-hardening comes within reach
for full-field integrated computational materials engineering. Moreover,
the integration of experimentally characterized microstructures and
the use of user friendly simulation and evaluation tools render powerful
modeling approaches feasible for a broad materials science user community.
The state of the art and future trends of mechanical, thermodynamic,
and kinetic continuum modeling of metallic materials at the grain
scale are outlined in this prospective article.
