Mittelineaarne staatiline analüüs (viskoelastsus)¶
Selles analüüsis kasutatakse kataloogi tutorial/07_viscoelastic_cylinder andmeid.
Analüüsiobjekt¶
Analüüsiobjekt on sama ümarlati 1/8 mudel nagu jaotises Mittelineaarne staatiline analüüs (hüperelastsus, osa 1).

Analüüsi protseduur¶
Käivitage FrontISTR-i käsk fistr1.
(Käivitatakse 4 lõimega.)
Analüüsi tulemused¶
REVOCAP_PrePostiga loodud deformeerunud kuju koos von Misesi pinge kontuuridega on näidatud joonisel 4.7.1. Tegu on analüüsi tulemusega 2 sekundi järel (10. samm). Arvuliste tulemustena on allpool toodud osa analüüsi tulemuste logifailist.
