Experimental research on effect of opening configuration and reinforcement method on buckling and strength analyses of spar web made of composite material

This study experimentally investigates the effect of the opening configuration on the buckling stability and bearing performance of a structural beam web used in a commercial aircraft made of composite materials. The buckling and strength analyses on three opening configurations (circular, oblong, a...
