Nonlinear static analysis (hyperelasticity sehemu ya 1)¶
Kwa uchanganuzi huu, tumia data katika tutorial/03_hyperelastic_cylinder.
Kitu kinachochanganuliwa¶
Kitu kinachochanganuliwa ni modeli ya 1/8 ya round bar; umbo lake linaonyeshwa katika Mchoro 4.3.1 na data ya mesh katika Mchoro 4.3.2.

Mchoro 4.3.1 Umbo la round bar (modeli ya 1/8)
Mchoro 4.3.2 Data ya mesh ya round bar (modeli ya 1/8)
Maudhui ya uchanganuzi¶
Tunafanya stress analysis kwa kutoa tensile displacement katika mwelekeo wa mhimili wa round bar. Modeli ya Mooney-Rivlin hutumiwa kama hyperelastic constitutive law. Data ya udhibiti wa uchanganuzi imeonyeshwa hapa chini.

Matokeo ya uchanganuzi¶
Kwa matokeo ya substep ya 5, deformation plot yenye contour ya Mises stress imeundwa kwa REVOCAP_PrePost na kuonyeshwa katika Mchoro 4.3.3. Pia, sehemu ya faili ya log ya matokeo imeonyeshwa hapa chini kama data ya nambari ya uchanganuzi.
