Running requirements | Installation | License
- calculate the normal stress & shaer flow & shear center of open profile or close profile with single or multi-cells.
- Use the Engineering Beam Theory to simplify the profile geometry properities.
- Show accurate calculate information of results, display figures of normal stress and shear flow distribution,the number of profile node , the location of shear center.
- calculate normal stress & shaer flow & shear center of open profile.
- calculate normal stress & shaer flow & shear center of close profile of single cell.
- calculate normal stress & shaer flow & shear center of close profile of multi-cells.
- plot profile with different thickness.
- plot normal stress and shear flow.
- report the shear flow experssion between each two nodes.
- the profile move to its centroid when calculation, the shear center is the relavite location.
- the Project just a simple demo of the Engineering Beam calculation, the deformation like restricted torsion didn't take into consideration.
- ...
- the input xy data is the actual loation of profile, in the calculation need the Sx=Sy=0, the Jxy=0 is not necessart.
-
the brief theory and formula
- normal stress in profile section,
,
- shear flow in open profile
.
- shear flow in close profile wuth three cells
The Sx and Sy should calculate from the free edge of the profile, when the profile is a close one, you should choose a cut point and the order of profile nodes is very important during calculation.
