On the project

V rámci řešení projektu budou získány nové poznatky o materiálových vlastnostech a spolehlivosti nosných mostních konstrukcí vyrobených z korozivzdorné oceli. Mezní stavy budou analyzovány s použitím numerických modelů založených převážně na nelineární metodě konečných prvků. Vstupními parametry výpočtových modelů budou reálné materiálové chrakteristiky obdržené z experimentů a zpracované do histogramů. Životnost mostních prvků bude teoreticky zkoumána s užitím lineární lomové mechaniky a geometrických funkcí zpracovaných s užitím únavových experimentů v laboratoři. Analýza spolehlivosti bude zahrnovat statistickou, citlivostní a pravděpodobnostní analýzu. Zajímavá zjištění lze očekávat u velmi štíhlých prvků s imperfekcemi, které obecně mohou mít vyšší napjatost, nižší odolnost a rychlejší únavovou degradaci v porovnání s pruty z uhlíkaté oceli. Zcela nové poznatky jsou očekávány od laboratorních experimentů zkoumajících únavové degradační procesy, které ještě nebyly pozorovány u existujících mostů, které jsou na začátku svého životního cyklu.

Description in English
New knowledge on the material properties and reliability of load-bearing bridge structures constructed from stainless steel will be obtained within the framework of the project. The limit states will be analysed using numerical models based primarily on the non-linear finite element method. The input parameters of the computational models will be real material characteristics obtained from experiments and processed into histograms. The lifetime of bridge members will be theoretically investigated using linear fracture mechanics and geometry functions proposed using fatigue experiments in laboratory. The reliability analysis will include statistical, sensitivity and probability analysis. Interesting findings can be expected for very slender members with imperfections that generally can have higher stress, lower resistance and faster fatigue degradation in comparison with carbon steel bars. New findings are expected from laboratory experiments investigating fatigue degradation processes that have not yet been o
