Originální abstrakt

In this work, a special multilayer piezoelectric cantilever energy harvester with active piezo-electric and protective ceramic layers is suggested and studied. Fracture mechanics behavior of such a layered structure is analyzed by means of the analytical model. Namely, the resistance of the structure to propagation of surface cracks upon harmonic vibrations is studied. The apparent fracture toughness of the laminate (which takes thermal residual stresses induced from processing into account) is calculated using the weight function method. The maximal allowable acceleration of the beam´s clamped end, which is applied upon a given forcing frequency and which warrants that the potential surface cracks will not propagate through the multilayer structure, is determined for a suggested configuration of the energy harvester.
