Abstract: | This paper studies the mode III crack problem of two bonded functionally graded piezoelectric half planes which contain a
crack respectively. These two cracks are located normal to the interface. All the material properties are assumed to vary
along the direction of the crack line. A system of singular integral equations for electrically impermeable and permeable
cracks is derived and solved numerically by using the Gauss–Chebyshev integration formula. The influence of the nonhomogeneous
parameters and the dependence of the crack interactions on the stress and electric displacement intensity factors are investigated. |
