A study into optimization of stiffeners in plates subjected to shear loading

It is also shown that the optimum geometric properties of the stiffeners correspond to the point when the buckling shape of a plate changes from the overall mode to local mode. Furthermore, all stiffened plates, with a similar aspect ratio and number of stiffeners, have a specific value of EIs/aD, for which the critical shear stress is optimal. In addition, some expressions to predict these properties are presented.
