Using Combined Experiments and Analysis to Generate Dynamic Critical Stress Intensity Data

Source

In this paper the authors give a short description of a finite-element model of mixed-mode dynamic crack propagation. They then discuss the use of combined experiments and analysis procedures to generate critical stress-intensity data as a function of crack velocity. Because of the sensitivity of the analysis to the boundary conditions and specified crack velocity, it is difficult to generate reliable KID(v) data using this approach. This is due to uncertainties in both the analysis and the measured crack position. Suggestions are made for alternate test methods to reduce some of these uncertainties.
