Résumé	The pressure-area curve shows that the observed ice failure pressure is proportional to the inverse square root of the loaded area. Two recent heuristic models for explaining this are compared and found to be modeling the same roughness profile, the self similar surface of fractal dimension 1.5, with nonstationary RMS roughness proportional to L1/2. The scale effect is alternately explained through a load sharing mechanism, Bhat (1990). A modification of the load sharing mechanism is shown to be necessary in light of the nonstationarity of the profile.
