Computational Homogenization of Transient Heat Conduction

Övrigt konferensbidrag, 2008

A Variational Multiscale Modeling framework, combined with a generalized macro-homogeneity condition, is exploited for the analysis of nonlinear transient heat conduction in a strongly heterogeneous particle composite. For the special case of a linear problem, a model-adaptive approach is adopted based on duality arguments which devises a low cost ’work model' wherever appropriate in order to reduce the computational cost.
