Interactive Buckling Effects in Stiffened GRP Panels.

Pagination or Media Count:
Results are described of a numerical study of the initial compressive buckling and post-buckling behaviour of GRP panels reinforced by longitudinal hat-section stiffeners. Particular reference is made to the effects of interaction between local buckling of the panesl laminate and overall, column-like buckling involving bending of the stiffeners. Conclusions are reached regarding the influence of interactive effects on collapse strength and recommendations are made on allowance for these effects in design. Great British.
