Abstract.The problem of determining the thermal stresses and displacement fields in an infinite orthotropic plane containing a pair of equal collinear Griffith cracks when the shape of the cracks prescribed is considered. An integral transform technique, based upon displacement potential, is employed for the case of steady-state temperature field. Numerical results of the stresses for different forms of the prescribed displacement are presented in graphs.
