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 کاملEffect of Grinding Parameters on the Fracture Toughness of WC–10Co–4Cr Coating Deposited by HVOF
Nowadays, application of cermet coatings deposited by High-Velocity Oxygen-Fuel (HVOF) has received considerable attention in a variety of industries. Carbide coatings have high surface roughness, so it is essential to grind the coated surface. The present investigation studied the effect of simultaneous changes in the grinding parameters including the depth of cut, feed rate and cutting sp...

متن کاملFracture toughness of dental composites determined using the short-rod fracture toughness test.
Plane strain fracture toughness (KIC) has been evaluated for a number of commercially-available dental composites. A modified Short-rod Fracture Toughness (SRFT) specimen design has been used, enabling small specimens to be tested conveniently. The effect on KIC of aging in water at 37 degrees C for seven days, one month, and six months has been determined for conventional, microfilled, and hyb...
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...
