“…The analysis of deformation and fracture behaviors, particularly the ductile-brittle transition behavior of steel, by recording the load-time or load-deflection curve during impact has been attempted since the 1920s [22]. Figure 6 shows a representative load-time curve and fracture surface in the transition region [23].…”

“…The author has developed a method of obtaining the propagation resistance Tmat by the analysis of the load-deflection curve of a single precracked specimen, as well as the dynamic elastic-plastic initiation fracture toughness value Jd (instead of JId when validity has not been verified). This method enabled the dynamic fracture toughness parameters to be obtained for the first time in the 1980s [11,22,[27][28][29]. It is also applicable to the Instrumented impact test of brittle materials [30][31][32].…”

It has passed one century since French G. Charpy proposed the Charpy impact test in 1901. Instrumented impact test recording load history during fracture has been attempted since 1920's. It has become possible to obtain various information from this method. However, succeeding development of fracture mechanics has made it also as a qualitative screening test. To obtain quantitative fracture toughness parameters from this method, therefore, has been desired eagerly. The author developed successfully a computer aided dynamic fracture toughness evaluation system , called CAI system already in 1980's. This paper reviews development and progress in the Charpy test, especially focusing on problems of evaluation of dynamic fracture toughness by the Instrumented impact test and on accuracy of measurement in the test.
