The role of Computer Aided Engineering in research as well as product development has been significantly increased during two last decades. The growing demands on the simulation address not only monodisciplinary phenomena but also phenomena from
different engineering branches. The current state-of-the-art simulation tools allow two basic approaches for meeting the demands, either coupling of various specialised simulation codes or application of multiphysical simulation tools.
This paper focuses on the simulation approaches for the multidisciplinary tasks and particularly on the connection of specialised simulation tools by interfaces. It classifies the interfaces between specialised software packages in general and gives some case studies using the coupling of specialised simulation tools. Finally, the development stages of an interface between civil and mechanical systems are presented. and Obsahuje seznam literatury
Autogenous deformation is a phenomenon that origins in chemical shrinkage during the cement hydration. The physical mechanism is the consumption of capillary water during the hydration and the refinement of capillary porosity. The microscopic underpressure due to thermo-dynamical equilibrium in a pore exerts the negative pressure on the solid skeleton of the paste. This behavior is simulated by means of FEM, where the microstructure of cement paste is loaded directly by underpressure. Validation shows that creep of the cement paste must be also taken into account when good quantitative prediction is expected. and Obsahuje seznam literatury
