Web[ 181. We then try to identify the crack tip coordinates from ti. 3. Methods of solution The extracted arrival-time data from experimental responses will probably not be exact. We propose two catalogues of methods to locate the crack tip under this situation. Sections 3.1 and 3.2 in the first catalogue are Web3 Crack Growth Predictions. Investigations of crack growth have mainly used growth criteria based on the stress intensity factor, the J-integral, or measures of the crack tip opening. However, the material models described in the previous chapter allow for a micromechanically based approach when the growth mechanism is ductile failure.
