  This is a technical note aiming at the re-examination of the phenomenon of
the steady-state cracking in the two-layer system. The method of Suo and
Hutchinson, as introduced in their 1989 paper, is followed. Our solution is
compared with the one appearing in that paper for the substrate-to-film
thickness ratio $\lambda_0=10$. We obtain results at three $\lambda_0<10$
values. Combined with the results for $\lambda_0=10$, the new sets of values
cover thickness ratios between 1 and 10, sufficient for determining crack
initiation and propagation in almost every relevant problem. We present our
results in tables (and figures), thus facilitating their implementation and
use.
