Department TW04: Mechanical Construction and Production

- Fracture mechanics of large-scale structural elements
- Mechanics of fibre reinforced materials
- Non-destructive material testing, characterisation and monitoring
- Experimental mechanics
- Tribological properties of materials
Actual research domains concerning materials technology:

- Fracture propagation in pipelines and off-shore constructions
- Weldability of metals
- Experimental investigation of fatigue of structural elements
- Experimental and numerical research on the static and dynamic behaviour (impact and fatigue) of fibre   reinforced composites
- Non-destructive monitoring of mechanical constructions by means of optical sensors
- Non-destructive characterisation of material properties (ultrasonic)
- Optical deformation measurement techniques (Moiré, speckle, holography...)
- Friction materials for brakes and clutches
- Diamond like carbon coatings for wear-resistant applications
- Friction at elevated temperatures of polymers for bearings
Specific test equipment and/or available techniques:

- extensive basic equipment for experimental material research (microscopes, oscilloscopes, transient   recorders, hardness testers, surface roughness testers...)
- universal testing machines and machines of own desifn for static tests (100 kN to 12000 kN)
- three servo-hydraulic machines for fatigue testing (100 kN to 1000 kN)
- extensive facilities for static and fatique testing of large-scale structural elements (modular ad hoc set up   depending of the test elements and loads; 15 servo-hydraulic cylinders are available)
- 3 impact facilities (1 vertical set up, 2 pneumatic accelerators; masses ranging from 10 g to 5 kg,   velocities from 0 to 200 m/s)
- 2 Hopkinson set ups for high strain rate material testing (tension and compression)
- 2 high speed cameras (1 rotating drum camera with film speeds up to 200 m/s, 1 framing camera   allowing up to 1 million images/s)
- ultrasonic scan installation with six degrees of freedom- small autoclave and filament winding machine for   the production of fibre reinforced parts
- different lasers (among which one pulsed laser), light sources and cameras for optical deformation   measurements
- 5 tribometers for friction, lubrification and wear testing (2 rotating, 2 reciprocating and 1 large-scale   reciprocating facility)
