ADVANTEST 9. Servohydraulic testing unit for compression, flexure, splitting tests.

Product Code: 50-C9842

CONTROLS with over 40 years experience within the field of materials testing, working alongside customers in industry and research establishment, has resulted in the most comprehensive range of testing systems, software and test accessories currently available.
The constant innovation and modern design applied to our testing systems, in cooperation with State Universities, has resulted in the development of the ADVANTEST 9 Servohydraulic testing unit.

General Description
The unit consists of:

Hydraulic power system
Microprocessor control unit
User interface with large graphic display and keyboard, PC and printer
Interactive software for PC.

The ADVANTEST 9 can control up to 4 hydraulic testing frames, of various dimensions and capacities, to perform tests under controlled speed of:

Load/stress (e.g. MPa/s; kN/s; etc.)
Displacement (e.g. m/s; pm/s)
Strain (e.g. strain/s).

The feedback is automatically performed with P.I.D. closed loop control.
The system controls the displacement of the hydraulic piston as a function of the load or stress or strain by a suitable transducer. The displacement transducer is placed by the user where needed to measure for example the deflection of a beam under flexure load. The strain transducers are typically fixed on the specimen for direct reading.

Main Application:
The performances of the ADVANTEST 9, besides to the conventional applications where the test ends with the failure of the specimen are related to the more advanced applications as the determination of the:

Concrete post peak residual strength
Concrete fracture toughness, from the complete Hardening + Softening Load vs. Strain diagram
Determination of the Elastic modulus.

The increasing use of new materials in the construction industry has created an increasing demand for new and more complex and sophisticated tests often related to the Deformability and Ductility behaviour.
The Ductility is a fundamental design parameter, which is related to the seismic risks, micro-fissure due to shrinkage, the fatigue behaviour, the resistance to shocks.

Typical construction materials tested for ductility
The materials, which are increasingly tested for Ductility are the following:

Fiber reinforced concrete (FRC) Conforming to UNI 11039-2, EN 14651 ASTM C1018
Sprayed concrete Conforming to UNI 10834, EN 14488-3, EN 14488-5
Concrete with polymer fibre lining (FRP) and other similar materials.

Advantages of the ADVANTEST system
In spite of the complexity of the above tests the ADVANTEST 9 remains a simple and easy machine to use for both conventional applications and research purposes. The outstanding Flexibility of the system allows a wide range of test and load applications from few kN to 5000 kN, as it has been specially designed and developed for the construction industry.
The result is an extremely convenient Quality and Performances/Price ratio.
