Statična analiza (lezenje)¶
Ta analiza uporablja podatke iz tutorial/08_creep_cylinder.
Predmet analize¶
Predmet analize je isti model 1/8 okrogle palice kot v Nelinearni statični analizi (hiperelastičnost, 1. del) v razdelku 4.3.

Postopek analize¶
Izvedite ukaz FrontISTR fistr1.
(Izvajanje s 4 nitmi.)
Rezultati analize¶
Rezultati 5. podkoraka so prikazani na sliki 4.8.1. Z REVOCAP_PrePost je izdelan deformacijski prikaz s konturami von Misesove napetosti. Spodaj je kot numerični podatek rezultatov analize prikazan del dnevniške datoteke rezultatov.
