Experimental-theoretical analysis of the state of stress and strain of stiffened glass-reinforced plastic shells subjected to local loads

The state of stress and strain of stiffened glass-reinforced plastic shells subjected to local loads applied to the stiffeners is investigated with allowance for interlaminar shear strains over the thickness of the glass-reinforced plastic. The solution is based on Vlasov's semimembrane theory. A comparative experimental-theoretical investigation has been made using models subjected to radial and axial loads and twisting moments.
