Uchanganuzi tuli usio wa mstari (elastoplastic 1)¶
Uchanganuzi huu unatumia data katika tutorial/05_plastic_cylinder.
Kitu cha uchanganuzi¶
Kitu cha uchanganuzi ni modeli ya 1/8 ya fimbo ya duara, sawa na ile ya uchanganuzi tuli usio wa mstari (hyperelastic 1).

Maudhui ya uchanganuzi¶
Tunachanganua hali ya necking ya fimbo ya duara inayosababishwa na mgeuko wa plastiki. Modeli ya Mises hutumiwa kwa yield function. Data ya udhibiti wa uchanganuzi imeonyeshwa hapa chini.

Utaratibu wa uchanganuzi¶
Tekeleza amri ya FrontISTR fistr1.
(utekelezaji kwa threads 4)
Matokeo ya uchanganuzi¶
Kwa matokeo ya substep ya 35, mchoro wa umbo lililogeuka wenye contour ya Mises stress umetengenezwa kwa REVOCAP_PrePost na umeonyeshwa katika Mchoro 4.5.1. Sehemu ya faili ya logi ya matokeo pia imeonyeshwa hapa chini kama data ya nambari.
