| Abstract | Article history: Received 21 November 2016 Received in revised form 17 January 2017 Accepted 28 January 2017 Available online 7 February 2017 A contactless video crack opening displacement gauging systembased on digital image correlation techniquewas established to measure the load-line displacement of miniaturized fracture toughness samples precisely. The intrinsic fracture toughness and smoothly rising R-curve of bulk dynamic plastic deformation (DPD) Cu with nanotwin bundles embedded in nano-grained matrix were measured through elastic-plastic unloading compliance method using miniaturized side-grooved compact tension specimens. Nanotwin bundles exert positive bearings on enhancing the damage tolerance of the DPD Cu. © 2017 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved. |
