Advanced Mechanical Testing Facility (AMTF)

Description

Advanced Mechanical Testing Facilities (AMTF) consists of following facility Planar Biaxial System – 100kN: This system employs multiaxial loading technology to apply and measure in-plane stresses in both the X and Y axes .It is a Servo-hydraulic testing machine with 4 actuators each having a capacity of 100 kN. All the actuators can be controlled independently. We can apply monotonic as well as fatigue loading in both x and y directions simultaneously. a) Axial Torsion Test System-250kN/2000Nm b) Axial Fatigue System- 100kN c) Rotary Bending Fatigue System- 20 Nm d) Digital Image Correlation (DIC) 2. Axial Torsion Test System-250kN/2000Nm: Axial/torsional testing simulates the multiaxial stress states of real-world operating conditions more accurately. Axial/torsional loading of tubular specimens offers a proven, highly valuable method for investigating material response to multiaxial static and fatigue stresses. Specimens are typically thin-walled tubes, and the stress states in the tube walls are mathematically well-known. Tests involve simultaneous application of torque and axial loading with some prescribed phase relationship. 3. Axial Fatigue System- 100kN: It is a versatile, high-performance servo hydraulic system for static and dynamic materials and component testing. It is proven MTS application software and has a complete selection of accessories to provide highly accurate and repeatable static and dynamic testing across the material testing continuum. 4. Rotary Bending Fatigue System- 20Nm: It is used to determine the bending fatigue property of round specimens under rotating load. During determination of the bending fatigue strength the specimen is subjected exclusively to alternating loading in order to obtain a mean value between zero positive and negative loads of equal magnitude. The rotating bar bending fatigue test can also be performed with an optionally available high temperature furnace at elevated temperatures up to 10000C. 5. Digital Image Correlation (DIC): DIC is a non-contact optical technique to measure strain, deformation and vibration which uses image processing to map the values across the whole specimen. It gives deformation values of in-plane as well as out-of-plane dimensions.
