Abstract: Presentations are sought that incorporate important microstructural information for simulating dynamic materials behavior at the macro-scale. New analytic material models and numerical techniques that are able to effectively describe material response are encouraged. Hierarchical models that incorporate a combination of deformation, localized damage and failure mechanisms, and which are consistent with each other are also of interest. Talks are solicited for a wide range of materials: polycrystalline, poly-phase metals and alloys, composites, ceramics, porous foams, cellular, bio-materials (bio-mimetic/bio-inspired), etc. Topics relevant to this symposium, include but are not limited to: -Microstructure generation incorporating features such as, distribution of grain-boundary types, dislocation densities and their gradients, poly-phase structures, texture and data from tomographic techniques. - Modeling (implicitly or explicitly) microstructural features and their evolution within a continuum framework, e.g. flaws/defects, through homogenization, stochasticity in material properties, implementation of micromechanics-based constitutive models. - Validations of advanced models based on experimental measurements of microstructural evolution - Bridging length and time scales. - High performance multi-scale simulations.
