Description
A small-scale machine that fits on a benchtop and allows simple tensile tests of metal specimens up to a maximum load of 20 kN. This machine is a good partner to TecQuipmentâs Torsion Testing Machine (SM1001). The machine has an extruded aluminium bed that holds the load application and load measuring mechanisms. âTie barsâ add rigidity to the structure.
The load application mechanism includes a hand-driven worm-and-wheel gearbox, driving a lead screw with approximately 400 mm of travel. The mechanism uses self-aligning ball thrust races in the direction of loading. These low-friction bearings, with the large handwheel allow the user to apply maximum load with minimum effort. They also give smooth and progressive operation, necessary to help the user apply a steady strain rate for best results.
The unit also has a smaller âquick advanceâ handwheel that allows the user to set the distance between the chucks simply and quickly before each test.
The load measuring mechanism is a strain-gauged load cell that connects to a microprocessor-controlled digital display. The load display unit has a âpeak holdâ function to register the maximum load before the specimen breaks. A sliding digital display measures the tensile displacement (extension) over the entire movement. An optional precision extensometer (SM1002A) is available for increased strain measurement accuracy to allow measurements of the materialâs Youngâs Modulus. Both the load, extension and extensometer displays can connect to TecQuipment’s optional VDASÂŽ.
The tensile specimens mount between the load application mechanism and load cell, in collet chucks via ball-jointed spigots. This ensures purely axial loading.
The equipment includes collet chucks to fit both the long and short style of TecQuipmentâs 20mm2 specimens. TecQuipment supply a starter set of tensile specimens with the machine, made of two different carbon steel alloys (each in their âas drawnâ and their annealed condition), brass and aluminium.
TecQuipment can also supply extra specimens (contact our sales team for details). The User Guide includes drawings to allow the user to make their own specimens if needed.
For quick and reliable tests, TecQuipmentâs optional VDASÂŽ gives accurate real-time data capture, monitoring and display, calculation and charting of all important readings on a computer.
Key features:
- Bench Top Tensile Testing Machine designed for student use
- Simple hand-operated load application for safe and easy operation
- Digital displays of load and overall displacement
- Supplied with chucks for standard 20 mm2 specimens
- Complements TecQuipmentâs Torsion Testing Machine (SM1001)
- Optional Extensometer (SM1002A) for Youngâs Modulus tests
- Optional Compression Cage and Brinell Test Set (SM1002B and SM1002C)
- Works with TecQuipmentâs Versatile Data Acquisition System (VDASÂŽ)
Learning outcomes:
- Tensile tests up to 20 kN on specimens made of different metals, to find material characteristics such as upper and lower yield strengths, tensile strength and overall extension.
- Tests of Youngâs Modulus (E) for the specimen material (needs SM1002A and TL specimens).
