摘      要：A new computational procedure for modelling the structural behavior of stiffened plates with symmetry boundary conditions is here *** uses two-dimensional finite elements as a way to decrease computational time without losing precision thanks to a relatively small number of elements applied for analyzing out-of-plane displacements(deflections)and ***,the constructal design method was included in the procedure,together with the exhaustive search technique,with the scope to optimize the stress/strain status of stiffened plates by design *** the purpose,a reference plate without stiffeners was initially design and used as starting *** of the volume was reshaped into stiffeners:thickness was reduced maintaining unchanged weight,length and *** main goal was to minimize strains and stresses by geometric *** demonstrated that,thanks to this design procedure,it is always possible to find an adequate geometry transformation from reference plate into stiffeners,allowing significant improvements in mechanical behavior.
