| Abstract | The Charpy test is one of the most important mechanical testing of materials. Which has interesting advantages like low costs, simple interpretation of the results and manufacturing sample facilities. However, instrumented Charpy test has shown better results because it was possible to obtain a dynamical reaction from impact load. The main problem is how could be acquire a dynamical signal without any external pertubation. This article results the use of signal acquisition architecture to determine the dynamic fracture toughness of metallic materials. Using extensometry principles, the striker of a Charpy machine was instrumented in conformity with ISO 14.556(2000). The rehearsed material was the AISI 4140 steel in having normalized. The evaluation the signal force measured was done compared the toughness read from dial on machine(Wd) and the toughness calculated from load-line displacement estimated (Wi). |
