Determination of Size Independent Fracture Energy for Regular Masonry
Original language description
The masonry constructions have been widely used for a long time. Nowadays, new masonry structures are on demand owing to its variety and appealing mechanical properties. Both basic components, i.e. the stone blocks and mortar joints, are viewed as quasi-brittle materials with inherent strain softening response, which (in dependence on fracture toughness of both components) manifests itself by the localization of inelastic strains mainly into the mortar beds between stones. With reference to their topology it appears useful, at least for computational purposes, to treat these material systems in the framework of multi-scale modeling based on homogenization techniques for the determination of material parameters on the mesoscopic level. The PUC serves asa suitable tool to determine the effective thermo-mechanical properties (namely the effective fracture energy) of the masonry and macroscopic loading paths that become the input data for the modeling on macroscopic level.
