Material testing possibilities:

  • Tensile-, compression-, bending-, torsional tests
  • Axial-, torsional- and biaxial fatigue tests (LCF, HCF)
  • Fracture mechanics tests (KIC, JIC, DKth, dadN)
  • Fatigue tests of structures and products
  • Static loading tests of products
  • Charpy impact tests (instrumented tests too)
  • Drop weight tests (instrumented test too)
  • Hardness tests (HBW1…5, HV0,05…HV10, HRC, SHORE)
  • Instrumented hardness tests (ABIT)
  • Surface Roughness test
  • Determination of dynamic properties of plastic (DMA)
  • Quality tests of welds
  • Biomechanical tests (implants and prosthesis)
  • SmallPunch (SP) test
  • Metallographic tests (micro and macro)
  • Layer thickness determination on cross section
  • Determination of remaining stress (with hole drilling test method, with instrumented hardness test method)
  • Determination of strain, deflection, torsion (with extensometers, strain gauges, deflectometer)
  • Determination of temperatures (distribution of temp.)

Most important material testing machines:

mechanikai-anyagvizsg

Instron 8850 Biaxiaxial (axial-torsional) universal servo-hydraulic material testing equipment

The equipment can carry out static and fatigue tests, with complete PC control. The equipment has two actuators (an axial and a torsional), that can be controlled together and independently also. The actuator is in the upper crosshead. The T-slot table at the bottom of the equipment allows you to test even larger structures, components. The following quantities can be measured during testing: force, torque, displacement, rotation, axial and torsial strain, and transversal strain deformation.

Instron 8803 universal servohydraulic fatigue testing system

Universal servohydraulic fatigue testing system, which performs static and dynamic tests on materials and its components. Its console software provides full system control from PC.
The actuator is at lower table base. The equipment can measure the following quantities: force, displacement, axial and transversal strain deformation.

The available temperature depends on the temperature tolerance of the clamp and the extensometer, that is used in the test. In our climate chamber and high temperature furnace we can carry out tests between -150  and +1400 °C temperature.

Instron 8874 Biaxial (axial-torsion) versatile servohydraulic material testing system

The equipment can carry out static and fatigue tests. Its controll software provides full system control form a PC. The equipment has two actuators (an axial and a torsion), that can be controlled together and independently also. The actuator is in the upper crosshead. The T-slot table in the bottom of the equipment allows you to test even larger structures, components. The equipment can measure the following quantities: force, torque, displacement, rotation, axial and torsial strain, and transversal strain deformation.

In the case of fatigue tests, the available maximum frequency is approximately 30 Hz in the axial direction, and approx. 10 Hz by rotation. The actual maximum frequency depends on the amount of the displacements or rotations.

Instron E 10000 Biaxial (axial-torsion) electro-dynamic testing machine

The equipment can carry out static and fatigue tests, and its control software provides full system control from a PC. The equipment has two actuators (an axial and a torsion), that can be controlled together and independently also. The T-slot table in the bottom of the equipment allows to test even larger structures. The equipment can measure the following quantities: force, torque, displacement, rotation, axial and torsial strain, and transversal strain deformation.

In the case of fatigue tests, the available maximum frequency is approximately 100 Hz in the axial direction, and approx. 30 Hz by rotation. The actual maximum frequency depends on the amount of displacements or rotations.

All the tests can be controlled and evaluated by the software. The measured values (time, force, torque, displacement, rotation, strain) ​​can be stored, so we can use them for further evaluations.
