Abstract:
Scattering o f SH w ave on crack in functiona lly graded/ piezoe lectric layers is d iscussed. Fourier transform s are used to reduce the prob lem to the solution o f a pa ir of dua l integra l equations, w hich are then reduced to a Fredho lm integ ra l equation of second k ind by the Copson m ethod. Fina lly, num er ica l resu lts show ed the effec t of ma teria l g radient, the frequency o f wave and so on upon the no rma lized stress intensity factor.
