About One Algorithm FEM Calculation of Construction Elements and Mechanisms in Case of Defects Presence
Key words: FEM calculations, data vat localized cracks, stress concentration, Special finite elements.
Annotation: The article contains the approach of FEM calculation of dynamic characteristics stress-strain of elements of buildings and structures in the presence of localized cracks. Accounting for stress concentration enters the group Special finite elements to accurately take due account order particularly busy at crack tip. The proposed algorithm can significantly reduce the time of calculation when storing accuracy.
