Contact analysis (sehemu ya 3)¶
Kwa uchanganuzi huu, tumia data katika tutorial/11_contact_2beam.
Kitu kinachochanganuliwa¶
Uchanganuzi huu ni tatizo la contact kati ya beam mbili; muhtasari wa analysis model unaonyeshwa katika Mchoro 4.11.1.

Mchoro 4.11.1 Muhtasari wa analysis model
Maudhui ya uchanganuzi¶
Tunafanya contact analysis kwa Lagrange multiplier method kwa kutoa prescribed displacement kwenye end face ya beam ya juu. 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 100, deformation plot yenye contour ya Mises stress imeundwa kwa REVOCAP_PrePost na kuonyeshwa katika Mchoro 4.11.2. Pia, sehemu ya faili ya log ya matokeo imeonyeshwa hapa chini kama data ya nambari ya uchanganuzi.
