Determination of basic and fracture-mechanics properties of materials.

Screw driven testing machine ZWICK Z50

Contact: prof. Ing. Ivo Dlouhý, CSc.
A universal testing system predominately used for quasi-static tensile, compressive, bending experiments of polymers, metals, ceramic and their composites at wide range of temperatures.

Universal test system INSTRON 8862 with electromechanical actuator

Contact: prof. Ing. Ivo Dlouhý, CSc.
A universal testing system predominately used for bending and compressive experiments of ceramic and ceramic composites at room temperatures.

High temperature impulse excitation technique IMCE HT1600

Contact: prof. Ing. Ivo Dlouhý, CSc.
The system allows obtaining temperature dependence of the elastic properties of the material by non-destructive impulse excitation method.
