Transient response of an insulating crack near to the interface between two piezoelectric half-planes under electromechanical impacts by BEM
چکیده انگلیسی

A time-domain boundary element method (BEM) together with the sub-domain technique is applied to study transient response of an insulating crack near to the interface between two anisotropic piezoelectric half-planes under electromechanical impacts. The present time-domain BEM uses a quadrature formula for the temporal discretization to approximate the convolution integrals and a collocation method for the spatial discretization. Quadratic quarter-point elements are implemented at the crack tip. A displacement extrapolation technique is used to determine the dynamic stress intensity factors (DSIFs) and the dynamic electrical displacement intensity factor. Numerical examples are presented to show the effects of load combination, geometric configuration and material combination on dynamic intensity factors and dynamic energy release rate.
