Analise-inhoud

’n Nie-lineêre dinamiese analise word uitgevoer nadat die verplasing van die beperkte oppervlak in Figuur 4.12.1 beperk is en ’n gekonsentreerde las op die lasnodusse toegepas is. Die analisebeheerdata word hieronder getoon.

Analiseresultate

’n Tydreeks van die verplasing van ’n monitornodus (lasnodus, nodusnommer 3121) wat in die analisebeheerdata gespesifiseer is, word in Figuur 4.13.1 getoon en is met Microsoft Excel geskep. ’n Gedeelte van die monitornodus-verplasingsuitvoerlêer (dyna_disp_3121.txt) word hieronder as numeriese data vir die analiseresultate getoon.
