Published Online: April 28, 2009
...B. Neethi Simon; K. Ramesh Transient thermal stresses of a bimaterial specimen with interface cracks, under uniform cooling by convection, are analyzed by photothermoelasticity and a coupled temperature-displacement, finite element scheme. The stress intensity factors of the interface crack...

... with one or two relaxation times. Convection from the crack surfaces is allowed and for the latter two models is itself influenced by thermal relaxation. A dynamic steady state of plane strain is assumed. Fourier heat conduction is shown to dominate away from the crack edge at low speeds; solution behavior...
