Three-point Bending

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.
