| Description
| - Tato práce byla motivována potřebou vhodného modelu pro 3D analýzu výplňového zdiva kamenných mostů. Navržený model popisuje chování zdiva z lomového kamene na mezostrukturální úrovni. Základní složky zdiva, tj. kamenné bloky a maltové spoje, jsou považovány za kvazikřehké materiály. Jejich základním znakem je deformační změkčení, které (v závislosti na lomové houževnatosti obou materiálů) se projevuje lokalizací neelastických deformací hlavně do spár mezi kameny. Na rozdíl od běžných modelů, ve kterých jsou maltové spoje vystiženy kontaktními prvky, v navrženém modelu jsou kameny i malta popsány konečnými prvky. Pouze snížená soudržnost a tahová pevnost přechodové vrstvy kámen-malta jsou vystiženy přechodovými prvky a Mohr-Coulombovým zákonem. (cs)
- The present paper is motivated by the need of finding a suitable material model for a 3D analysis of filling masonry in stone bridges. The proposed model describes the behaviour of quarry masonry on mesostructural (mesoscopic) level. Both basic components, i.e. the stone blocks and mortar joints, are viewed as quasibrittle materials. Their basic feature is strain softening, which – in dependence on fracture toughness of both components – manifests itself by the localization of inelastic strains mainly into the mortar beds between stones. In contradiction to classical models, in which the behaviour of the mortar bed is described by means of contact elements, in the proposed model both the stones and mortar beds are discretized using finite elements. Only the reduced adhesion and tensile strength of the “stone – mortar” interface are then grasped by the contact elements and Mohr-Coulomb law.
