Analaytical Model

Hi all,

      If an analytical model predicts accurately all stresses, including transverse normal stress across thickness, using constitutive law for the analysis of laminated composite structures, what is the use of this model and where can  I apply this model in composite structures and fracture mechanics?. Further this model is amenable to linear/nonlinear finite elements with less degrees of freedom per node (C0 and C1 finite elements are possible).
