In many applications, from nanotechnology to construction and mining, the modelled objects are not large enough as compared to the material constituents for classical continuum modelling to be adequate, but yet encompass too many elements for comfortable particle-type computer simulation. Generalised continua would offer a viable option if a rational method of their construction for each intrinsic material structure were at hand. The project aims at developing the necessary homogenisation procedure and constructing generalised (Cosserat) continuum models of deformation, wave propagation and impact fracture in particulate and layered materials such as multi-wall nanotubes, fullerenes, particulate composites and layered rock masses.

在许多应用中，从纳米技术到建筑和采矿，与经典连续体建模的材料成分相比，建模对象不够大，但对于舒适的粒子型计算机模拟来说，它包含了太多的元素。广义连续统将提供一个可行的选择，如果一个合理的方法，他们的建设，为每一个内在的物质结构在手。该项目旨在开发必要的均匀化程序，并在颗粒和层状材料（如多壁纳米管，富勒烯，颗粒复合材料和层状岩体）中构建变形，波传播和冲击断裂的广义（Cosserat）连续模型。
