Enhanced Continuum Theories for Multiscale Modelling of Materials and Structures
Session Aims and Scope
Structural models based on classical continuum theory are widely used to get accurate engineering solutions at an affordable computational cost. However, they break down when capturing size effects, e. g. in modelling stress and strain due to singularities or in the prediction of wave dispersion. That is they become inadequate to describe the response when the characteristic length (or wave length) of deformation becomes comparable to the characteristic length of the microstructure. This is because classical theory does not accommodate information about the microstructure within the continuum model. This problem has been the focus of interest for many researchers on multiscale strategies, in which information from the lower scale migrates to the structural scale.

Within this context, enhanced or generalised continua that include additional terms are a possible approach to “fix” classical models. They incorporate into the governing equations additional degrees of freedom (micropolar), the spatial averages of the relevant fields (strongly non-local) or higher-order derivatives of the relevant state variables (gradient). All these theories are non-local in the sense that they include also a microstructural length scale parameter to account for the influence of a field variable at the neighbouring points. Despite the idea of enriched continua dating back the beginning of the 20th century, during recent decades there has been renewed attention towards the development of theories with easier engineering interpretation of the additional quantities and simpler numerical implementation.

The aim of this session is to bring together researchers working on problems successfully tackled with enhanced continuum theories. Contributions from members of the scientific community dedicated to a purely theoretical/analytical domain as well as studies pertaining to the computational/numerical and experimental territory are welcome.
