Nie-lineêre statiese analise (Elastoplastisiteit, Deel 1)¶
Hierdie analise gebruik die data van tutorial/05_plastic_cylinder.
Analisedoel¶
Die objek van analise is die dieselfde round staaf 1/8 model as in die Non-lineêre statiese analise (Hiperelastisiteit, Deel 1).

Analise-inhoud¶
Die necking phenomenon van 'n round staaf weens na plasties vervorming is ontleed. Die Mises model word gebruik om die vloei funksie. Die analytical beheer data is hieronder getoon.

Analisresultate¶
Die resultate van die 35th substap word getoon in Figuur 4.5.1. 'N vervormingsdiagram met die Mises spanning contours bygevoeg is geskep deur REVOCAP_PrePost. 'N deel van die analisresultate log lêer is hieronder getoon as numeries data vir die analisresultate.
