Analise-inhoud¶
’n Lineêre dinamiese analise word uitgevoer nadat die verplasings van die beperkte oppervlak in Figuur 4.12.1 beperk en ’n gekonsentreerde las op die lasnodus toegepas is. Die analisebeheerdata word hieronder getoon.

Analyseresultate¶
Die tydreeksvoorstelling van die verplasing van die moniteringsnodus wat in die analisebeheerdata gespesifiseer is (lasnodus, nodusnommer 3121), word met Microsoft Excel geskep en in Figuur 4.12.3 getoon. Daarbenewens word ’n gedeelte van die verplasingsuitvoerlêer van die moniteringsnodus (dyna_disp_3121.txt) hieronder as numeriese analyseresultaatdata getoon.
