In this paper, a closed-form solution is obtained for partially plated beams. Linear elastic behavior is assumed for beam, plate, and adhesive. The behavior of the adhesive is idealized using the Roberts and Haji-Kazemi model. A system of differential equations is obtained and finally solved by detecting the distribution of shearing stresses through the adhesive layer. All other beam resultants are obtained via equations of equilibrium. The approach has suggested a simple experimental device that enables the user to evaluate the stiffness parameters of the adhesive layer. Finally, the response of the model is compared with numerical solutions by finite element model and the experimental results obtained for flexural tests on partially plated beams. A good agreement is observed.
