Summary:A critical examination is conducted of the microfocus radiography (MR) and acoustic emission (AE) real-time methods for following crack-initiation propagation. It is shown that the combination of the two methods during mode I tests can clarify the interpretation of data, and is especially helpful in attributing a physical basis to the points taken from the load-displacement curve to characterize initiation; this is especially important when tough thermoplastic-matrix composites are being tested. Combined MR and AE shows great potential for understanding damage-accumulation processes. (O.C.)
