Description
| - Článek analyzuje různé alternativy modelování statistického vlivu velikosti na pevnost kvazikřehkých konstrukcí. Úloha spolehlivostních metod na úrovni náhodných veličin, teorii extrémních hodnot a klasická stochastická metoda konečných prvků s náhodnýmpolem pevnosti je prověřena s ohledem na schopnost podchytit dva zdroje vlivu velikosti: deterministický a statistický. Je použit příklad selhání po inicializaci trhliny; teoretické predikce jsou srovnány s experimentálnámi daty. (cs)
- This paper analyzes various modeling alternatives for the statistical size effect in quasibrittle structures. The role of reliability techniques, encompassing the classical reliability theory at random variables level, the theory of extreme values in Weibull form, and the stochastic finite element method with random strength field, is examined with a view toward capturing both the deterministic and statistical size effects. The theoretical development describing deterministic and statistical size effeects is documented using the crack initiation problem. Theoretical predictions are compared with the existing test data.
