The problem of uniform heat flow disturbed by an insulated penny-shaped crack along the common plane between two semi-infinite elastic media with different thermo-mechanical properties is formulated in terms of two potential functions in a half-space which in turn is reduced to a plane problem solvable by Muskhelishvili's method in complex function theory. Explicit expressions for the stress-intensity factors and the local stress field are derived and used in conjunction with Griffith's energy criterion to obtain the critical temperature gradient which motivates and produces initial crack extension along the bonding surface. The stress analysis involved is also applicable to a penny-shaped crack between two dissimilar solids under shear loadings. |
