Kontakanalise (Deel 2)¶
Hierdie analise gebruik die data van tutorial/10_contact_2tubes.
Analisevoorwerp¶
Die analise is ’n silindriese indrukprobleem; die geometrie van die analisevoorwerp word in Figuur 4.10.1 en die maasdata in Figuur 4.10.2 getoon.

Analise-inhoud¶
Die Lagrange-vermenigvuldigermetode word gebruik om kontakanalise uit te voer deur die geforseerde verplasing in die indrukrigting aan die geforseerde oppervlak in Figuur 4.10.1 te gee. Die analisebeheerdata word hieronder getoon.

Analiseresultate¶
Die resultate van die vierde substap word in Figuur 4.10.3 getoon. ’n Vervormingsdiagram met Mises-spanningskontoere word deur REVOCAP_PrePost geskep. ’n Gedeelte van die analiseresultaat-loglêer word hieronder as numeriese data vir die analiseresultate getoon.
