reinforcement of plates with various aspect ratios against elastic axial buckling using externally bonded frp patches

in present paper, the buckling capacity of the plates was increased by externally bonding of the frp pultruded sheets on the plates. in order to indicate the effectiveness of the present technique, at first an analytical approach to the problem was conducted and then through finite element modeling, the influences of the composite patches with various characteristics were studied. the results introduce the present technique as a promising method for reinforcing of plates in the stability design consideration. for each part of the paper, useful graphs have been prepared in order to obtain the be t configurations of the composite patches for application of this technique with more efficiency.
