Formatted abstract
Edge chipping is a phenomenon that can occur when sharp edge of brittle material is
subjected to a force or an impulse. Knowledge of this behaviour has not been studied in
depth due to its insignificance in most applications since standards have mandated the
requirement of rounded edges for safety issues. This phenomenon can be beneficial in
understanding fracture mechanics.

Ball Mill Edge Chipping Test is currently being developed as it has the potential to
revolutionise research particularly in fracture resistance of white cast iron. Results from the
tests can be used to evaluate fracture toughness with a few advantages as compared to the
conventional methods of evaluating fracture resistance such as Charpy impact test and
ASTM E399 KIc test. Being able to do repeat experiments without consuming too much alloy
stock and time, unlike the other conventional tests, Ball Mill Edge Chipping Test seems to be
able to provide much better validation of fracture resistance measurements. This thesis is
first aimed to produce information on optimal operational characteristic needed to achieve
the best results through a series of tests. These tests will investigate the effect of impact
velocity, cushioning, initial edge radius, specimen size and surface finish on edge chipping.
Once these operational characteristics information have been collected, Ball Mill Edge
Chipping Test will commence and it is aimed to evaluate different alloy performance. To
correlate this phenomenon with science engineering, slow-strain tests, finite element stress
analysis and macroscopic and microscopic laboratory tests will be conducted.
To conclude, Ball Mill Edge Chipping Test is a very useful laboratory test that has the
potential of standing side-by-side with other famous conventional methods such as Charpy
impact test and ASTM E399 KIc test with a few advantages as compared to others.
