What is the torsion test?

The

torsion test measures the power of any material against maximum bending forces. It is an extremely common test used in the measuring mechanics for measurement, how much bend a certain material lasts before rupture or breaking. This applied bending pressure is referred to as torque. Materials that are usually used in the processing industry, such as metal fasteners and rays, often test torsion testing to determine their strength under pressure.

There are three wide categories according to which a torsion test can take place: testing of faults, evidence testing and surgical testing. Testing faults involves twisting the material until it breaks. Testing the evidence observes whether the material can carry a certain amount of torque burden in a given period of time. Operating testing tests specific products to confirm their elastic limit before continuing the market.

It is essential to record the results of each torsion test test. Record is madeThe stress strain of the diagram with an angle of reversal values ​​on the x -axis and the torque values ​​on the Y axis. Using a torsion test device, twisted is carried out with a quarter -degree with torque that can be recorded. The trunk corresponds to the angle of reversal and the voltage corresponds to the measured torque.

The elastic limit of any material is a point where it can no longer return to the original shape or size. The elastic limit of the torsional test is equal to the lines of the line from the beginning of testing to the proportional limit. This relationship was first measured by Sir Robert Hooke in 1678. Hooke's law states that stress is directly proportional to the voltage until the proportional limit is reached, at this point the tested object begins to show signs of stress.

After testing, metal materials are categorized as towing or fragile. Metals such as steel or aluminum have a high elasticThe limits and last a large voltage before breaking. Fragile materials such as cast iron and concrete have low elastic limits and do not require much stress before rupture.

Without a torsion test, the materials would not be properly checked before release for industrial use. It is primarily important that the ability of the material to carry a certain amount of twisting and bending is measured precisely. Otherwise, structures and machines that depend on such materials can analyze instability, interruption of working flow or even significant damage and injury.
