The Dynamic Behaviour of the Instrumented Charpy Test
The dynamic characteristics of the Charpy test have been studied by means OF a Hopkinson bar apparatus and photoelasticity. It is Found that this technique permits a clear evaluation of the test results, and is preferable to the standard instrumented pendulum test.
متن کاملExperimental and Numerical Investigation of Rock Dynamic Fracture
Rapid development of engineering activities expands through a variety of rock engineering processes such as drilling, blasting, mining and mineral processing. These activities require rock dynamic fracture mechanics method to characterize the rock behavior. Dynamic fracture toughness is an important parameter for the analysis of engineering structures under dynamic loading. Several experimental...
متن کاملThe Effect of Microstructure on Estimation of the Fracture Toughness (KIC) Rotor Steel Using Charpy Absorbed Energy (CVN)
The proportional relationships between the Charpy absorbed energy (CVN) and the KIC values have been established for a wide variety of steels. Several formulae have been proposed that predict KIC from CVN. The purpose of this study is to investigate, by means of compact testing fracture toughness specimens, the effective role of microstructure for estimation of the fractur...
