Application of the Theory of Critical Distance (TCD) to the Breakage of Cardboard Cutting Blades in Al7075 Alloy
The study presented in this paper was undertaken in response to two instances of unexpected blade breakage in the cutting blade used in a Carton Wrap machine (CW).Failure of the Al7075 alloy blade occurred at an indentation during typical operational loading conditions.Subsequent metallographic examinations of the fractured samples confirmed that b
