What is Instron testing?
The Instron Test System is a stand-alone, fully digital, single-axis controller that is packaged as a tower. It uses a motor encoder and a load cell to collect data during tension, compression, and 3-point bend tests.
What is the fatigue test used for?
Fatigue tests are performed to measure the reduction in stiffness and strength of materials under repeated loading and to determine the total number of load cycles to failure. Fatigue tests are performed by repeated tension–tension, compression– compression, tension-compression or other combinations of cyclic loading.
What does Instron machine measure?
Strain Measurement Instron’s AVE2 can measure changes to specimen length down to ±1 µm or 0.5% of reading. Tensile testing machines are available in a variety of different sizes and force capacities ranging from 0.02 N to 2,000 kN.
What is an Instron load cell?
Instron load cells are an integral part of the load weighing system of a testing machine. Instron load cells are tested for accuracy and repeatability on a calibration apparatus traceable to international standards, with an uncertainty of measurements not exceeding one third of the permissible error of the load cell.
How is a fatigue test performed?
To perform a fatigue test a sample is loaded into a fatigue tester or fatigue test machine and loaded using the pre-determined test stress, then unloaded to either zero load or an opposite load. This cycle of loading and unloading is then repeated until the end of the test is reached.
What is fatigue tensile test?
3. Fatigue testing is defined as the process of progressive localized permanent structural change occurring in a material subjected to conditions that produce fluctuating stresses and strains at some point or points and that may culminate in cracks or complete fracture after a sufficient number of fluctuations.
How do I turn on Instron?
Turn on power to the Instron. The power switch is on the right bottom rear of the frame. 3. You will see a countdown begin on the display on the left hand side of the instron, which will countdown to 2 and remain at 2 until the Bluehill program is opened on the computer.
How do you calibrate an Instron load cell?
Simply click on the load cell icon, and then click “Calibrate”. We refer to this as a software calibration (or “soft-cal”), which also balances the load cell. Here are some soft-cal quick tips: We recommend that the machine and load cell be switched on for about 15 minutes prior to performing a soft calibration.
