A closed-form analytical solution of the dynamic stress distribution of the fiber reinforced polymer (FRP) rod is presented in this paper. It is derived based on a trilinear model from a boundary shear stress of the FRP rod. The dynamic stress distribution of the FRP rod during the pull-out process can be modelled by this analytical solution, which is correlated against experimental data. Especially, the stress distributions of the rod at six evolution points are studied. This analytical solution offers a new approach for predicting the ultimate load bearing capacity of the FRP rod.
