Using Stroh's formalism and conformal mapping, Green's functions are o
btained in closed-form for an infinite thermopiezoelectric plate with
an elliptic hole induced by temperature discontinuity. The Green's fun
ction satisfies free-traction-charge as well as thermal-insulated cond
itions along the hole boundary. Based on the Green's function, a syste
m of singular integral equations for the unknown temperature discontin
uity defined on crack faces is developed to study the interaction betw
een crack and elliptic hole. Numerical results are presented to elucid
ate the effects of crack orientation on stress and electric displaceme
nt (SED) intensity factors and to illustrate the application of the pr
oposed Green's function. (C) 1998 Elsevier Science Ltd. All rights res
