Triaxial Testing of Biomaterials

For triaxial testing of biological tissues, ZwickRoell offers triaxial low-load testing machines with maximum test loads of up to 20 N. These testing machines enable specimens to be loaded simultaneously along three axes that are perpendicular to each another. A distinction is made between testing machines for triaxial shear testing and testing machines for strain, torsion, and bulge testing.

Key Advantages and Features

Strain, bulging, and torsion testing machine

  • Low-load testing machines for the mechanical characterization of biological tissues such as cardiovascular tissues, arteries, the esophagus and trachea
  • Loading the specimen with axial force (strain), internal pressure (bulging), and rotational movement (torsion)
  • Tissue specimens submerged in a physiological solution
  • Optical measuring systems enable exact measurement without influencing the specimen
  • Non-contact videoXtens measures the axial strain and change in width simultaneously
  • Non-contact laserxtens for measuring torque

Tensile, compression, and shear testing machine

  • Low-load testing machine for measuring the shear force of biological (orthotropic) tissues
  • Upper platform (in the Z direction) vertically displaceable, achieved by precision, low-loading testing machine for compression loading
  • Lower platform (X and Y directions) horizontally dipslaceable, achieved by precision linear module for shear loading
  • Simultaneous force measurement in three orthogonal directions (X, Y, and Z direction) via 3-axis load cell for extremely small forces and for low crosstalk of the force axes.
  • Testing software via graphical sequence editor for graphically supported generation of individual test sequences with multiple axes
  • Temperature conditioning vessel: Glass basin for measuring specimens in physiological and temperature conditioned liquid
