The effects of rubber content and temperature on dynamic fracture toughness of ABS materials have been investigated based on the J ‐integral and crack opening displacement (COD, δ) concepts by an instrumented Charpy impact test. A multiple specimens R‐curve method and stop block technique are used. It is shown that the materials exhibit a different toughness behavior, depending on rubber content and temperature. The resistance against stable crack initiation ( J 0.2 or δ 0.2 ) increases with increasing rubber content. However, J 0.2 first increased with increasing temperature until reaching the maximum value; after that, it decreases with further increasing the temperature. © 2000 John Wiley & Sons, Inc.
