Information × Registration Number 0215U000272, 0112U000479 , R & D reports Title "Loss of efficiency of the nonelastic thin-walled elements of constructions with sensors and actuators at the harmonic electromechanics loading". popup.stage_title Head Sichko Viktor Mihaylovich, Registration Date 05-02-2015 Organization The Mykolayiv V.O.Sukhomlynsky National University popup.description2 In carrying out the project developed and reasonably simplified equation of state of physically nonlinear passive and piezoactive materials at harmonic load method for determining the parameters of simplified equations of state at monoharmonical deformation developed approximate model of forced harmonic vibrations and dissipative heating thin elements with inelastic passive and physically piezoactive nonlinear materials, numerical and analytical methods for solving problems of vibration and dissipative heating of thin piezoelements. Criteria thermal destruction of thin-walled structural elements of inelastic piezomaterial at harmonic vibration, which is based on the achievement of dissipative heating temperature Curie point of the active material. Based on the developed models and methods investigated resonant bending vibration and dissipative heating of thin plates and shells of physically nonlinear materials and calculated critical values of mechanical load, after which a thin-walled piezoelement achieve losing its functionality because of the loss of active piezoelectric material.
