The paper presents a new model for interlaminar normal stress distribution in moderately thick and singly curved laminates. It requires in-plane strain information which must also map the kinematical effects caused by the curved laminate shape. The number of free parameters of the exact solutions for each layer is reduced and determined by a finite-element procedure which is also explained. The results of the mechanical model are compared with FEM results for unidirectional and cross-ply laminates. The new model can be developed for element-level post processing in a FEM program with simple finite structural elements.
