Dynamic anti-plane characteristic on an infinite piezoelectric medium with a movable rigid cylindrical inclusion
TL;DR: In this paper, a movable rigid cylindrical inclusion with a complex variable and wave function expansion method is studied for an infinite elastic piezoelectric medium, and the results show that dynamic stress concentrations at the edge of the inclusion have linear dependence on the incident electric field.

TL;DR: In this article, the authors examined the fracture toughness of lead zirconate titanate (PZT) under quasi-static and stress-wave loading conditions and found that the critical stress intensity factor increased seven to tenfold compared to static fracture toughness values, with poled samples exhibiting the greatest toughness.
