摘要：

We report experimental evidence that the velocity of a crack, in brittle materials, can be considered as a control parameter which determines several properties of the crack dynamics. Above a critical speed the crack develops an instability associated with a strong sound emission and a strong increase of the surface roughness. Both phenomena seem to be two efficient mechanisms which allow the crack to dissipate energy.
