The sample is supported on two
edges, while the cutting end of the push rod applies a load to
the sample from above. The spacing between the two edges is in
accordance with DIN 53457. Four different free bending lengths
are available. This deformation mode is ideal for materials with
a high storage modulus such as filled or reinforced thermoplastics
and thermosets (composites) or metals and alloys.
Dual Cantilever Bending
The ends of the sample are tightly
clamped. This arrangement is especially suitable for samples of
mid modulus range (rubber and thermoplastics). Holders for three
different bending lengths are available. By leaving one end of
the sample free, measurements can be made in the single cantilever
bending mode as well.
Compression
The sample (rubber, foams, biopolymers,
pasty materials, etc.) is placed on a flat surface in the sample
holder and pressure is applied from above with the plate-shaped
end of the push rod. Different diameters up to 30 mm are available.
If the end of the push rod is pointed rather than flat, the term
is penetration. For example, this type of stressing is suitable
for the investigation of coatings.
Linear Shearing
Two identical samples are pressured
or glued in sandwich geometry between the flat surfaces of the
sample holder and the push rod. The load is applied via the platelike
extension of the push rod. Two types of sample holders are especially
suitable for soft materials such as rubber or adhesives.
Tension
The tension mode is preferable
for the measurement of films and fibers or thin rubber samples.
The lower end of the sample is held in place, whereas the upper
end is clamped to the oscillating push rod.
