Pendulum impact test apparatus are designed to measure the resistance to failure of a material to a suddenly applied force.
Could
you give an overview of how motorized pendulum impact testers work and
how these compare to different types of impact testing systems?
Motorized pendulum impact machines provide a safe alternative to manual
pendulum impact machines which typically do not have CE compliant guards
and require the operator to manually lift the hammer to its release
position. The hammer assembly is very heavy to help achieve higher
initial energies required to test modern high toughness materials. For
example, the Instron MPX 450J hammer assembly weighs 32 Kgs. Not
surprisingly, it will be difficult for an operator to lift the hammer to
150 degrees between each test which can lead to operator fatigue and
possible repetitive motion injuries. A motorized pendulum impact system
eliminates this risk to the operator.
Could you explain the Charpy and Izod standards and why these are so important in impact testing?
Airplane
and automotive components, OCTG (oil country tubular goods), ship
hulls, etc. will experience impacts during field use. Impact testing is
critical to understanding how these materials will perform in real-life
conditions. ASTM E23 and ISO 148 are the most common standards for
impact testing. Charpy and Izod nomenclature refers to the method of
testing carried out to meet the standards. ISO 148 requires the Charpy
method and ASTM E23 permits both Charpy and Izod methods. Charpy testing
specimens are supported by a beam with a V- or U-notch cut out in the
same plane that the striker will pass through, undergoing three-point
bending. An Izod specimen is held in a cantilevered manner where the
striker will hit the top of the specimen. Charpy impact testing for
metals applications is most common.
