The notch in the sample affects the results of the impact test, thus it is necessary for the notch to be of regular dimensions and geometry. The size of the sample can also affect results, since the dimensions determine whether or not the material is in plane strain. This difference can greatly affect the conclusions made.

convenient sample geometry for the tensile test is the "dogbone" geometry (Figure 1). In this test geometry, one end of σ = F A (1) i i o i = l (l ) ε ∆ (2) σ = Eε (3) NOTE: In this paper the author is reporting values as (mean value) +/- (standard deviation ) of the data. For ME Lab I, you will usually report your values as (mean

Many specifications talk of a transition temperature, a temperature at which the fracture behaviour changes from ductile to brittle.This temperature is often determined by selecting, quite arbitrarily, the temperature at which the metal achieves an impact value of 27 Joules - see, for example the impact test requirements of EN 10028 Part 2 Steel for Pressure Purposes.
Jul 14, 2018· Aggregate Impact Value Test. AIV test is conducted to determine the Aggregate Impact Value of Coarse aggregate. The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from Its resistance to a slow compression load.
Impact test involves the sudden and dynamic application of the load. For this purpose, in general, a pendulum is made to swing from a fixed height and strike the standard impact specimen. There are two types of method to test impact test which is Izod test and Charpy test. These two methods are different in placing the specimens.

Izod Impact Test: In the Izod impact test, the test piece is a cantilever, clamped upright in an anvil, with a V-notch at the level of the top of the clamp. The test piece is hit by a striker carried on a pendulum which is allowed to fall freely from a fixed height, to give a blow of 120 ft lb energy.
Jul 16, 2014· Aggregate impact value test gives an indication of aggregate's toughness property (i.e. property of a material to resist impact) Aggregate impact values are used to classify the stone aggregates with respect to toughness property as given below. Aggregate impact value (%) Toughness Properties <10 Exceptionally tough / Strong 10 – 20 Very tough / Strong […]
The test sample consists of aggregates passing 12.5mm sieve and retained on 10mm sieve and dried in an oven for four hours at a temperature 100 0 C to 110 0 C and cooled. Test aggregates are filled up to about one-third full in the cylindrical measure and tamped 25 times with rounded end of the tamping rod.

The tensile load and corresponding extensions are then recorded for calculations and determination of stress- strain relationship of the material specimen. The tensile test experiment can be used to determine other mechanical characteristics of the specimen like yield strength, percentage elongation, and ultimate strength among others.
