Mchoro 4.6.2 Data ya mesh ya container
Maudhui ya uchanganuzi¶
Tunazuia displacement ya uso wa kizuizi ulioonyeshwa katika Mchoro 4.6.1 na kufanya stress analysis kwa kuweka distributed load kwenye uso wa ndani wa container kama loaded surface. Modeli ya Drucker-Prager hutumiwa kama yield function. Data ya udhibiti wa uchanganuzi imeonyeshwa hapa chini.

Utaratibu wa uchanganuzi¶
Tekeleza amri ya FrontISTR fistr1.
(Huendeshwa kwa thread 4)
Matokeo ya uchanganuzi¶
Kwa matokeo ya substep ya 10, deformation plot yenye contour ya Mises stress imeundwa kwa REVOCAP_PrePost na kuonyeshwa katika Mchoro 4.6.3. Deformation scale ni 30. Pia, sehemu ya faili ya log ya matokeo imeonyeshwa hapa chini kama data ya nambari ya uchanganuzi.
