An analysis of cavitation failure incorporating cavity nucleation with strain
An analysis of cavitation failure incorporating cavity nucleation with strain
Cavitation failure is analyzed for the condition where there is a continuous nucleation of cavities with strain. A failure criterion is established by assuming that catastrophic fracture occurs when the cavities coalesce. A computer program was developed to calculate theoretical creep curves and times to fracture, and the predictions of the analysis are compared with experimental data. The analysis shows that a decrease in stress leads to (i) an increase in the importance of the strain due to cavity growth and (ii) a decrease in the number of cavities per unit area observed at constant strain. These predictions are consistent with the anticipated behavior.

Abstract
Cavitation failure is analyzed for the condition where there is a continuous nucleation of cavities with strain. A failure criterion is established by assuming that catastrophic fracture occurs when the cavities coalesce. A computer program was developed to calculate theoretical creep curves and times to fracture, and the predictions of the analysis are compared with experimental data. The analysis shows that a decrease in stress leads to (i) an increase in the importance of the strain due to cavity growth and (ii) a decrease in the number of cavities per unit area observed at constant strain. These predictions are consistent with the anticipated behavior.
