Scratch tests : a new way of evaluating the fracture toughness of materials
(Massachusetts Institute of Technology, 2011)
This thesis develops, validates and implements a fracture mechanics model for the assessment of the fracture toughness of materials from scratch tests. Dimensional Analysis highlights two major processes at work during ...
Assessment of fracture properties and rate effects on fracture of materials by micro scratching: application to gas shale
(Massachusetts Institute of Technology, 2013)
Since 1921, several experimental methods have been implemented to measure the Griffith fracture energy. The challenge lies in providing a measure that is intrinsic and invariant with respect to external factors such as ...
