Purpose - to address a number of new challenges for the fracture mechanics of bodies with cracks at the interface between piezoelectric and piezomagnetic materials. Research methods - methods of complex variable theory and finite element method. Obtaining accurate analytical and numerical solutions of plane problems for interfacial fracture zones contact its banks in the isotropic and the piezoelectric / piezomagnetic bimaterialah by mechanical, thermal, electrical and magnetic influences. The influence of external pressures on the stress field in the vicinity of the crack tip and the stress intensity factors and electric induction. Investigated piezoelectric composite with a crack in the adhesive layer which is in the field of remote-tensile shear load. Crack analyzed with finite electrical and magnetic permeability in the piezoelectric / piezomagnetic remote space under the action of mechanical load, the electrical and magnetic fluxes. The numerical analysis of the process of destruction of piezoelectric and ferroelectric materials with regard to the reorientation of domains and using the exponential accumulation of cyclic cohesive model of damage. All results are new and match the world level, which was confirmed during the presentation of the results at international scientific conferences and publications in leading international journals. Areas of application: aviation, rocket science, microelectronics.
