Abstract: Based on 3D fundamental equations of elasticity and by assuming boundary displacement functions associated with free edges, the state equation for orthotropic laminated plate is established and a analytical solution for rectan gular plate with two opposite free edges and two opposite simply supported edges is presented. The given solution satisfies all fundamental equations of elasticity and continuity conditions between the laminates. The presented method can be used to treat free edges of laminates flexibly. The examples show a higher accuracy of this solution.
Keywords: laminated plates, boundary displacement functions, state equation, ana lytical solution.
