Measuring fracture properties using digital image and volume correlation: decomposing the J-integral for mixed-mode parameters

MR Molteno - 2017 - scholar.sun.ac.za
The degradation of material properties over time is one of the core constituents of structural
integrity monitoring. For this purpose, the materials' resistance to brittle fracture is the most …
