Kontakanalise (deel 3)¶
Hierdie analise gebruik die data van tutorial/11_contact_2beam.
Analiseteiken¶
Die analise is ’n kontakprobleem tussen twee balke, en ’n oorsig van die analisemodel word in Figuur 4.11.1 getoon.

Analise-inhoud¶
Die Lagrange-vermenigvuldigermetode word gebruik om ’n kontakanalise uit te voer waarin ’n voorgeskrewe verplasing aan die eindvlak van die boonste balk gegee word. Die analisebeheerdata word hieronder getoon.

Analiseresultate¶
Die resultate van die 100ste substap word in Figuur 4.11.2 getoon. ’n Vervormingsdiagram met Mises-spanningskontoere word deur REVOCAP_PrePost geskep. ’n Deel van die analiseresultaat-loglêer word hieronder as numeriese data vir die analiseresultate getoon.
