This paper presents a simple analytical method to solve the response histories of dynamic stresses and transient electric potential in piezoelectric fibers subjected to radial impact. From analytical expressions and calculation results for two kinds of piezoelectric fibers, PZT-4 and BaTiO 3 it is found that dynamic focusing-effects of dynamic stresses and transient electric potential at the...
Based on finite Hankle transforms, this paper presents a theoretical method for analyzing the dynamic focusing effect of piezoelectric fibers subjected to the thermal shock of a transitory temperature change produced by a sudden electric current pulse. From analytical expressions and example calculations for two kinds of piezoelectric fibers, PZT-4 and BaTiO3, it is found that the dynamic focusing...
