| Description
| - Sendvičové konstrukční prvky, tj. prvky tvořené dvěma potahy a jádrem, vynikají vysokým poměrem ohybové tuhosti ku hmotnosti konstrukce. Celek je navržen tak, aby jádro přenášelo smykové síly a potahy ohybová zatížení. Sendvičové konstrukce je možno modelovat metodou konečných prvků (MKP) s využitím vrstvených skořepinových prvků, kombinací skořepinových a objemových prvků nebo pouze objemovými prvky. Pro srovnávací analýzu byl jako zkušební těleso vybrán sendvičový nosník tvořený kombinací potah-jádro-potah. Srovnání jednotlivých metod modelování bylo provedeno pro případ tříbodového ohybu. Tuhost modelů byla srovnána prostřednictvím průhybů. Dále byly srovnávány průběhy deformace a napětí po tloušťce nosníku. Průhyby nosníků byly porovnávány s experimentálními daty. Jako nejvhodnější způsob modelování se jeví modelování potahu skořepinovými a jádra objemovými prvky. (cs)
- Sandwich construction elements, i.e. elements formed by two skins and core, excel in high ratio of bending stiffness to weight of construction. This complex is designed in order to transmit transverse forces by core and bending load by skins. It is possible to model these constructions by finite elements method (FEM) with use of layered shell elements, by combination of shell and solid elements or by only solid elements. As a test body was chosen sandwich beam composed by combination skin - core - skin for comparative analysis. Comparison of particular model method was carried out for case of three-point bending. Model stiffness was confronted by beam deflection. Further there were confronted variation of strain and stress along thickness. Beam deflections were compared with experimental available data. As optimal model is appeared modelling of skins by shells and core by solid elements.
