Abstract
Recently, a simple procedure based on the relationship between crack length
and absorbed energy was provided to determine the crack length from the load–
displacement test record. This procedure was validated on a large number of
materials using various cracked geometries. The main objective of this paper is to
investigate the possibility to apply a similar procedure to a V–notched geometry,
namely the Charpy specimen. Such an evaluation would lead to estimate the
material crack resistance from a single Charpy V–notched impact test.
By performing a number of well–selected experiments, we demonstrated that
such a correlation exists, allowing the determination of both static as well as
dynamic (impact) crack resistance from the simple instrumented Charpy impact
test with a reasonable accuracy.
