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 ...
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 ...
