Nie-lineêre statiese analise (Hiperelastisiteit, Deel 2)¶
Hierdie analise gebruik die data van tutorial/04_hyperelastic_spring.
Analisedoel¶
Die veer is die objek van die analise, die geometrie is getoon in Figuur 4.4.1 en die maasdata is getoon in Figuur 4.4.2.

Analise-inhoud¶
'N spanning analise word uitgevoer deur restraining die verplasing van die beperk oppervlak getoon in Figuur 4.4.1 en toepassing 'n verplasing na die belasting oppervlak. Die Arruda-Boyce model word gebruik as die konstitutief model vir die hiperelasties materiaal. Die analisebeheerdata is hieronder getoon.
