| Abstract |
The next generation of computer-aided design (CAE)
simulation software will integrate nano and micro structures into CAE
capabilities and software for design and manufacturing. We propose an
alternative concurrent bridging scale theory for the next generation of CAE
software. In particular, we wish to extend current FEM software to
incorporate the concurrent multiphysics in a single unified simulation.
These are fundamentally necessary to account for the multiple scale behavior
observed in material design. We briefly outline the development of
hierarchical and concurrent multiple scale governing equations for
heterogeneous systems, which include coupling of molecular dynamics and
continuum, and its associated bridging scale simulation methods. We will
then present bridging scale analysis of finite temperature of crack growth,
design of Cybersteel 2020 for naval ships, and the proposed design of the
next-generation alloys for aero and auto applications.
