Abstract

Effect of surface tension across a growth interface is known as the Gibbs‐Thomson effect, and the associated energy balance is widely referred to as the Stefan condition in the literature, which is derived from thermodynamics. In this article, the interface energy balance that accounts for the effect of surface tension is derived by writing the jump condition for the energy balance on a surface of discontinuity which represents in crystal growth the evolving growth interface (solidification front) between the liquid and solid phases. To the best of our knowledge, the derivation of energy balance by writing jump conditions on a surface of discontinuity (interface) is new. (Β© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Abstr&-There is a dramatic change in the shape of the semi-elIiptiad surface cracks, growing due to combined cyclic bending and tensile loading of plam. It is possibk to predict the change of aspect ratio (o/c) during the propagation of the crack. The growing cracks change their shapes such that the
