Nie-lineêre statiese analise (elastoplastisiteit, Deel 2)¶
Hierdie analise gebruik die data van tutorial/06_plastic_can.
Analisevoorwerp¶
Die analisevoorwerp is ’n 1/2-model van ’n houer. Die geometrie daarvan word in Figuur 4.6.1 getoon en die maasdata in Figuur 4.6.2.

Analise-inhoud¶
’n Spanningsanalise word uitgevoer deur die verplasing van die beperkingsoppervlak soos in Fig. 4.6.1 getoon te beperk en verspreide laste op die binnekant van die houer as ’n geforseerde oppervlak toe te pas. Die Drucker-Prager-model word vir die vloeifunksie gebruik. Die analisebeheerdata word hieronder getoon.

(Voer met 4 drade uit.)
Analiseresultate¶
Vir die resultate van die tiende substap-analise word ’n vervormingsdiagram met Mises-spanningskontoere deur REVOCAP_PrePost geskep en in Figuur 4.6.3 getoon. Die vervormingsfaktor is op 30 gestel. ’n Gedeelte van die loglêer word hieronder as numeriese data van die analiseresultate getoon.
