The effects of specimen dimension (thickness, width) and specimen configuration (SENB, CT), as well as test conditions (crosshead speed, temperature), over a range of crosshead speeds from 0.01 to 100 mm/min and temperatures from −40 to 60°C, on the crack growth resistance behavior were investigated in a commercial amorphous thermoplastic polyvinylchloride (PVC) using the J‐integral and crack opening displacement (COD) concepts. With the combined application of these two different fracture mechanics parameters, more detailed information on fracture processes can be obtained. The relationship between deformation mechanisms and fracture toughness was discussed through a comparative analysis of J versus Δa and COD versus Δa resistance curves. © 1997 John Wiley & Sons, Inc.
