HARDNESS TESTING - STARTER WORKSHEET
1) The following words describe properties of materials. Write the correct word in each
property box. Each word can only be used once.
PLASTIC, ELASTIC, DUCTILE, BRITTLE, HARDNESS, TOUGHNESS
2) Draw a line between each property and the picture of the material that you think best
represents that property.
DEFINITION
PROPERTY
The ability of a material to stretch
under the influence of an external stress
/ force, but to return to the original
shape and size once the stress / force is
removed.
A property due to the plastic
deformation of materials which allows
the material to be drawn out into a wire
or beaten into shape.
A measure of a materials resistance to
deformation. Tested by measuring the
extent of plastic deformation by a
standard indentation test.
The ability of a material to flow under
sufficient stress allowing changes in
shape without breaking. *******
deformation results in permanent shape
changes when atoms or molecules slide
past one another
The ability of a material to absorb
energy from an impact. To illustrate,
elastomers are soft and stretch easily.
By stretching they absorb energy from
an impact and are therefore very *****.
By contrast, ceramics are very hard,
but are also brittle, absorbing little
energy of an impact – these materials
are NOT *****.
A fracture with little or no plastic
deformation. The opposite of ductile.
