Abstract
Considered in this paper is a semi-infinite piezoelectric medium containing an edge crack perpendicular to the surface of the medium. The medium is subjected to a sudden cooling on its surface. The transient temperature and the stress distributions in an uncracked strip are calculated. This stress for uncracked medium is used as the crack surface traction with opposite sign to formulate the mixed boundary value problem. A singular integral equation of Cauchy-type is derived and solved numerically. The numerical results for the stress intensity factor are computed as a function of the normalized time and the crack size. The temperature and the thermal stress distributions for the uncracked problem are also included.
