Kurzfassung englisch:
This presented thesis is a compilation of six peer reviewed articles which are published in international scientific journals and covers multi-scale modelling in the field of computational solid mechanics. Two applications were selected from two distinct fields: Perforated laminates and human bone from the field of synthetic and natural composites, respectively.
Different methods were used to obtain homogenized material properties: the general method of cells (GMC), the mean field methods, and the finite element methods (FEM). Mainly periodic boundary conditions were employed in combination with finite element unit cell models. Kinematic uniform and a new set of mixed boundary conditions were additionally studied on material volume elements for the investigations of random porous media like e.g. trabecular bone. In both application fields multi-scale frameworks from the micro/meso to the macro-scale were presented and validated. Both multi-scale frameworks were designed such that they can be used for practical problems and represent steps towards the design of bio-inspired materials.
