Uchanganuzi Tuli (Creep)¶
Uchanganuzi huu unatumia data katika tutorial/08_creep_cylinder.
Kitu cha uchanganuzi¶
Kitu cha uchanganuzi ni modeli ileile ya 1/8 ya fimbo ya mviringo kama katika Uchanganuzi Tuli Usio wa Mstari (Hyperelasticity, Sehemu ya 1) ya Sehemu 4.3.

Maudhui ya uchanganuzi¶
Tabia ya creep huchanganuliwa kwa kuweka uhamisho wa mvutano katika mwelekeo wa mhimili wa fimbo ya mviringo. Data ya udhibiti wa uchanganuzi imeonyeshwa hapa chini.

Utaratibu wa uchanganuzi¶
Tekeleza amri ya utekelezaji ya FrontISTR fistr1.
(Hutekelezwa kwa thread 4.)
Matokeo ya uchanganuzi¶
Kwa matokeo ya substep ya 5, mchoro wa uharibifu wenye kontua za mkazo wa Mises unatengenezwa kwa REVOCAP_PrePost na kuonyeshwa katika Mchoro 4.8.1. Pia, sehemu ya faili ya logi ya matokeo ya uchanganuzi imeonyeshwa hapa chini kama data ya namba ya matokeo.
