متن کاملFlexural Properties and Fracture Behavior of Nanoporous Alumina film by Three-Point Bending Test
This study investigated the influence of porosity on the flexural property of a nanoporous alumina film. When the porosity of the alumina film increased, both bending strength and modulus declined. The results from the bending test revealed that the setting of the film during the bending test had significant influence on the flexural property. Fracture only occurred when the porous side of the ...
متن کاملThe 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 کاملLocal Approach of the Charpy Test at Low Temperature
Charpy V-notch impact testing is widely used in the toughness assessment of large forged components, e.g. the pressure vessel for pressurised water reactors m). At low temperature, A508 C1.3 nuclear pressure vessel steel fails by cleavage fracture. The results reported here are part of both an experimental program and numerical investigations which aim at the establishment of a non-empirical re...
متن کاملEffect of grain structure on Charpy impact behavior of copper
Nanostructured (NS) and ultrafine-grained (UFG) materials have high strength and relatively low ductility. Their toughness has not been comprehensively investigated. Here we report the Charpy impact behavior and the corresponding microstructural evolutions in UFG Cu with equi-axed and elongated grains which were prepared by equal channel angular pressing (ECAP) for 2 and 16 passes at room tempe...
