Torsion testing is important to measure the pressure of two materials. It can be used for acquiring information like torsional shear stress, maximum torque, shear modulus, and breaking angle of a material. It is a mechanical testing process that can be conducted with two materials and an axial. Materials are placed on the ends of an axial, and evaluate the pressure with a torsion tool under stress from angular displacement.
There are two types of torsion testing processes. It finds wider application in the field of mechanical engineering, where shear strength is a measure of some materials like plastic tubes and wires through stress on an axial, and functional testing is performed on the finished products like screws and pharmaceutical and sheathed cabins to test their strength. Through torsion testing, people can measure the elasticity, shear strength, modules and ductility of such materials or finished products.
Why would you need a torsion test?
Some products need torsion testing to upgrade the materials. For example, engineers can use such testing tools to change or update the materials used for their products. Each vehicle has some metals to drive the loads on the road, and we need to check the torsion capacity of such metals before we use them in our vehicles. It can save the fuel cost of a car. Mechanical engineers can save a car’s fuel and increase the load-bearing capacity and efficiency of a car by changing the metal used in the car. They have to reduce the car’s overall weight when choosing such heavy metals. In this case, engineers can perform such tests to identify such metals and materials to reduce the weight of a car and maintain fuel efficiency.
Apart from the automobile sector, you can find various products which have to pass through this torsion testing process. For example, biomedical tubes, electrical switches and fasteners are a few examples where torsion testing is necessary. After testing the torsion of such products, the manufacturer can change the materials used in their products, and they can change the design of their products to maintain the highest quality standard.
Different types of torsion tests
Engineers can use a rotational motion and place their materials on an axial to rotate their products in a particular motion to test the torsion of their products. Else, they can use torsional force to test their products. Two types of torsion tests are available: tension or compression test and torsional forces test.
- Torsional loads can be applied on a demo product to finalize the design of the main product.
- In the case of axial testing, materials are placed on the end of an axial and rotational force is applied on the axial to check the torsion strength of such products or specimens.
- Apart from that, a torsion test can be performed to check the fragility rate of a product. In this case, engineers can twist a specimen until failure and test the torsion strength until it breaks or defects.
- Engineers can also perform such tests on finished products to check their functionality and use such testing tools on various products like bottle caps, switches, dial pens, or steering columns.
Apart from that, you can find some materials used in your home which have been tested through torsion testing tools. For example, your garage door is designed with some springs, and you can move your door with the help of these springs. Garage doors are heavy, and it is very difficult to move such heavy doors with a few-inch spring. In this case, such springs are tested with mechanical force, and engineers can test the torsion or elasticity of such springs before they use them in your door. The torsion test is the accurate method to check the strength of such springs, and it is known as the incremental stress measurement process.
Wrapping it up !!!
So, if you want to modify your products made of metal or other materials, you need to check the torsion of your finished products and the materials used in your products. Through this testing process, you can reduce the weight of your products by changing the material and make it suitable for your requirement.
