Bench for characterizing the mechanical behavior of materials subjected to uniaxial or biaxial mechanical stress.


The mechanical characterization bench is designed to study the behavior of materials subjected to single-axis or double-axis mechanical loads. It can be used to generate uniaxial tensile or compressive stress states, or equibitraction, equibicompression or shear states for biaxial stresses. 

Specific piezoelectric actuators and their dedicated power supplies are employed to generate static or dynamic stress states.

Force transducers and strain gages are used to determine the strain-stress characteristics of the sample under test.

These mechanical characterizations can be coupled with electrical or magnetic characterizations.

Technical specifications:

For single-axis testing, specimens must have maximum dimensions of 13 cm by 4 cm. For bi-axial tests, samples should be cross-shaped, inscribed in a square measuring 13 cm by 13 cm, with cross arms no wider than 4 cm. Specimen thickness can range from 0.1 mm to 0.35 mm.

Depending on the specimen, stresses of up to 70 MPa can be developed quasistatically.

Load frequencies range from 0 to 10 kHz.
