Physico-mathematical modeling and informational technologies| Zusammenfassung: | An exact analytical approach to the analysis of plane deformation of piezoelectric bimaterial withelectroded electrically charged crack located at the interface of its components is proposed. It isassumed that the normal and shear stresses are established at infinity and an electric field isacting parallel to the crack faces. It is also allowed for the crack faces can contact along the zoneof an unknown length, adjacent to one of the crack tip. The combined Dirichlet-Riemann boundaryvalue problems is formulated and solved analytically. Using the contact conditions, the length ofthe crack contact zone and corresponding electromechanical characteristics are found. Thenumerical illustration of the solutions obtained is performed. It is shown that both a remoteelectric field and a total charge of the crack significantly affect the length of the contact area andthe electromechanical characteristics in the vicinity of the crack. |
