DETECTION OF NONLOCAL CALIBRATION PARAMETERS AND RANGE INTERACTION FOR DYNAMICS OF FGM POROUS NANOBEAMS UNDER ELECTRO-MECHANICAL LOADS

The present investigation examines the range of effect nonlocal parameters on dynamic behavior a smart beam-like nanostructure modeled as sandwich functionally graded porous nanobeam with piezoelectric layers. Therefore, study is concentrated determining length structure for which effects are observed vibration under in-plane electro-mechanical forces. nanobeam-based NEMS device model obtained based assumptions strain gradient theory in conjunction Reddy higher-order shear deformation theory. differences results nanostructure’s free classical and assumptions. To application different simply supported nanobeam, defined eigenvalue problem solved view variation to thickness ratio, distribution material properties, well loads. What more, attempts determine calibrate values size-dependent coefficients expected natural frequencies, applied completed extensive discussion dependence nanobeam’s response, thus may be an important step forward extend understanding ultra-small structure’s behavior.
