Abstract
Experiments are described of the separation at known velocity of uniformly thick oil films of various viscosities and initial thicknesses. Separation of the film occurred in patterned striations or in un-patterned direct cleavage. The width of the striations correlated approximately with the square root of the initial film thickness. This correlation includes other data in the literature. The calculated negative pressures in the striations suggest that the separation mode changed from striations to tensile cleavage at tensile stresses greater than about four atmospheres.
It appears that the rate of damage and the damage pattern in ASTM cavitation erosion tests can be correlated with the maximum negative pressure occurring in the striations.
