Toledo Metal Spinning PoP Cone Results

PoP-T10s video of buckling process
Stiffened cone.  This cone was scanned with the laser range finder prior to testing.  The zero datum for the depth into
the cone was set 1/2 inch along the cone wall from the top (large end) of the cone.  After the intial buckling of the cone,
additional laser scans were taken to give the shape of the buckled surface.
