This paper presents a detailed analysis of an anti-plane crack problem in polarized piezoelectric material layer, incorporating both strain and electric field gradient effects. The study focuses on arbitrarily oriented considers the influence polarization direction. face boundary is assumed to be semi-permeable, with electrical mechanical loads applied at layer boundary. Two characteristic length parameters, l 1 2 , are introduced capture effects, respectively. governing equations along relevant conditions derived. By applying eigenfunction expansion technique, singularity index established. Fourier transform then utilized into hypersingular integral equation. equation solved numerically using Chebyshev series approach. closed-form analytical expressions presented for various fracture including sliding displacement, opening potential drop, stress intensity factor, displacement condition parameter (ECCP). Bisection method used demonstrate convergence ECCP. An illustrative numerical case these parameters show effect direction, orientation crack, intrinsic lengths, loads.
