Hello, I am using the ACTB active bending feature to calculate the stress distribution and deformation of the 22 m length bar with a circular cross-section.
I used both ways suggested in the ASE manual and Teddy examples:
- Earlier application of Sofistik in which a straight beam is bent and analyzed with the full nonlinear geometric analysis.
- ACTB function.
I expect the model to act as an Elastica curve (regarding the deformations) but using the ACTB feature ends in the strange shape which is not really desired. (I should say I checked the available Teddy examples provided from Sofistik and the difference was the same!).
It seems that both simulated bars give “approximately” the same deformed shape but quite difference in the amount of displacements and not having the same curvature along its curvilinear axis.
Can you help me with solving this problem?
