Analysis of Panels with Flanged Stiffeners

(1/1)

MGerhardt:
Hello
I'm trying to understand the calculation of the ABD-matrices in Hypersizer. With the document "Methods and Equations - Thermoelastic Stiffness Formulation" I've great success, but nevertheless I've problems to understand the way Hypersizer calculates the ABD-matrix with flanged stiffeners. For Blades the explanation is comprehensible (chapter 8), but for flanged panels (chapter 9) only the assumptions are documented. How does Hypersizer calculates the ABD-matrix with flanges?
Best Regards

Ryan:
This is by design. We've chosen to keep the details of the bonded flanged ABD proprietary. Though technically you could derive the ABD manipulations given the assumptions.
