Void growth is analysed when a grain boundary contains a distribution of second phase particles. The rate of void growth is determined by the ease with which material can plate out around the particles or the rate at which the material surrounding the particln can deform by power-law creep.

Abstract
In this paper, an attempt has been made to investigate the temperature field in a twoโdimensional thermoelastic medium with voids. This takes place when it is subjected to a timeโdependent temperature source under the conditions of conduction heat transfer and interaction between the thermoelastic medium and its surroundings. Analytical expressions of displacements, stresses, temperature increment, and change in the volume fraction field for a layer of thermoelastic medium and a halfโspace thermoelastic problem are derived by using the Laplace and Fourier transformation techniques. Two scalar potential functions of the displacement are introduced in the solution process. Then, the integral transform is inverted by using a numerical technique, and numerical results are illustrated graphically to analyze the distribution of the fields. Furthermore, the influence of the thermoโvoid coefficient for two kinds of temperature boundaries is discussed. A comparison is also presented with the corresponding halfโspace thermoelastic model without voids to ascertain the validity and the difference between these models. ยฉ 2010 Wiley Periodicals, Inc.
