Compensation of stress intensity factors in hollow cylinders containing several cracks under torsion by electro-elastic coating

doi:10.1007/s10483-019-2520-9

Abstract

Abstract: In this article, a formulation for a hollow cylinder reinforced with an electroelastic layer is investigated. The hollow cylinder and its electro-elastic coating are under the Saint-Venant torsional loading. First, the solution to the problem containing a Volterra-type screw dislocation is obtained by using the Fourier transform. The problem is then reduced to a set of Cauchy singular integral equations by the distributed dislocation method. Finally, several examples are presented to show the effect of the electro-elastic coating on the reduction of the stress intensity factors at the crack tips.

Key words: hollow cylinder, electro-elastic coating, stress intensity factor, multiple arbitrarily oriented cracks, Saint-Venant torsion, electric displacement
