N2 - This paper develops one-dimensional and two-dimensional models for bending, coupled bending and extension of isotropic beams/plates with induced strain actuators. The adhesive layer between the actuator and the structure is considered in the Bernoulli-Euler formulation and the results for various models are compared with the uniform strain model which includes the shear lag effects with assumption of a finite thickness of adhesive layer. The reduction in actuation as a result of strain distribution inside the actuator is considered to improve the prediction ability of the existing model based on the Bernoulli-Euler formulation. The FEM model is also developed to study the strain transfer in the beam. Finally, an experimental test employing a macro fiber composite (MFC) actuator is carried out to evaluate the accuracy and limitations of the developed models. The models are in good agreement with the experimental results.
