Electroelastic stress in an electrostrictive material with charged surface electrodes

摘要: Field singularities of collinear electrodes on the surface a half-infinite electrostrictive solid are studied in terms complex variable method. Firstly, general solutions for potential functions electric fields and stresses derived case based analytical continuation Then, explicit results given cases one two electrodes, respectively. Finally, numerical calculations made to discuss effects applied loading field near electrodes. It is found that even at low level loading, considerable high will be induced around tip Moreover, multiple distribution more complicated than single electrode.
