This paper presents general antiplane electro-mechanical field solutions for a piezoelectric finite wedge subjected to a pair of concentrated forces and free charges. The boundary conditions on the circular segment are considered as traction free and insulated. Using the finite Mellin transforms method, the stress and electrical displacement at all fields of piezoelectric finite wedge are derived analytically; besides that, the singularity orders and intensity factors of stress and electrical displacement can be obtained too. After being reduced to the problem of an antiplane edge crack or an infinite wedge in a piezoelectric medium, the results compare well with those of previous studies.

Keywords:  Antiplane problem; Piezoelectric finite wedge; Generalized intensity factor
