We have followed the evolution of strain near the tip of an arresting cleavage crack in a pressure vessel steel using a strain gage technique. The measurements were made using a linear array of strain gages located along the intended crack path and 0.65B (B is the specimen thickness) above this plane. the gages were read using instrumentation capable of resolving strain in time intervals of between 2 and 4 µs. The results were obtained in a thick plate, large enough that reflected elastic waves did not contribute significantly to the strain records or crack motion during the time interval of interest. |
