Sectional Properties

Recommended Posts


One feature I have been looking for (that I don't think is available) is to be able to retrieve sectional properties from a number of cross sections or planar surfaces.

I am often doing structural analysis of hydrofoils and being able to retrieve sectional interia/torsion constant information and operate on them would be a huge help. 

https://github.com/robbievanleeuwen/section-properties is a potential option but I haven't had the time to try and integrate it myself.


Looking forward to seeing what CAESES 4.5 has in store for us ..

Typical 2D section properties we use are like this in appropriate unit system of course:

Area:                    92357056.735
Perimeter:               36720.890
Bounding box:         X: 1165.227  --  17331.991
                      Y: -329.077  --  11344.873
Centroid:             X: 8420.303
                      Y: 5290.858
Moments of inertia:   X: 3120718178929088
                      Y: 7513980514853601
Product of inertia:  XY: 3959967613135844
Radius of gyration:    X: 5812.892
                      Y: 9019.864
Principal moments and X-Y directions of centroid:
                      I: 4.856E+14 along [0.952 -0.306]
                      J: 1015503441212061 along [0.306 0.952]
