Procedure to Estimate the Crack Resistance Curve from the Instrumented Charpy V–Notched Impact Test

    Research outputpeer-review


    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.
