Honeycomb panel test
Honeycomb panel test
(OP)
Hi:
Recentlly we tested a composite panel for uniform pressure load and tablulated the deflection at few location where we were intersted.But when I tried to use hand equations to calculate the stiffness/deflection and I got totally diffefrent results for deflection.Actually deflections are more in hand eqations.
Now am I wondering which deflection to use to calculate stiffness.
If I use from hand results, stiffness (total load from pressure /deflection)is not acceptable because sfiffness is small than required.
Can anyone tell what I am missing?
Thanks in adwanse.

How was the load applied?
What boundary conditions were used in your analysis?
Is it a constant thickness panel, or do the facesheets ramp down into a laminate edgeband?
Have you included transverse shear deflection in your analysis?
