All That You Need to Know About Universal Testing Machine

Universal testing machines are used to measure the force being applied to various materials and the deformation that occurs as a result. They are commonly used for testing the strength of steel reinforcing bars while under tension. They can be used to conduct tests to determine a material’s shear, flex or bend, peel, tear, puncture or burst, friction, torsion, friction, heat distortion temperature, and stiffness, too. Some of the most common types of universal testing machines are hydraulic and electromechanical testing equipment, which are designed, developed, and manufactured to conform to various standards. Some machines can be more versatile with the addition of certain types of accessories, like load cells, fixtures, grips, and platens.

‘Universal’ pertains to the many different types of standard compression and standard tests on structure, components, and materials. A basic universal testing machine will have the components including the load frame that typically consists of two strong supports, and a load cell that must be calibrated periodically. The machine should come with an articulated cross head that can be moved up or down at a manually controlled or programmed constant speed. Universal testing machines have a means for measuring deformation or extension, like extensometers, and an output device to display the results of the test.

Some universal testing machines have special features, like controlled conditioning that lets you determine the compressive and tensile strength of materials under given conditions (i.e. pressure, humidity, and temperature). In that case, the machine can be placed in a special environment chamber or a controlled room. The method for setting up a universal testing machine will depend on the type of testing that you must do, but it must follow the specifications of a standards organisation for preparation, gauge length, analysis, fixturing, and other necessary tasks. If you need to conduct a specific type of test for a unique engineering solution, there are providers of universal testing machines that can create customised solutions with your requirements in mind.

Advantages of Universal Testing Machine

The main advantage of investing in a universal testing machine is that the device can be used to test the strength, durability, and suitability for most any material. A universal testing machine has the capability to pull, compress, bend, or stretch material to its breaking point. It is primarily used by laboratories that manufacture and or mould different types of plastics. A universal testing device features one or two vertical columns mounted on a base. A second horizontal plate contains attachments that are used to hold the sample and slides up and down during stress testing samples. Dual vertical column machines are preferred by most laboratories as they can handle larger samples in terms of size and weight. Determining tensile strength is the most common test performed in a universal testing machine. This is done by holding one end of a sample in place while the other is pulled away until two sides are torn apart. The same process is used for testing flexural str

Uses for Universal Testing Machine

Universal testing machine or UTM is aptly named as it can perform various types of tensile and compression tests on different materials. There are also many different terms used to refer to a UTM that you will commonly hear in the industry, among the most popular of which are a tensile tester, bend tester, and compression tester. Some types of UTMs are stripped of some capabilities and/or are marketed to specific sectors, like texture analyzers for food, peel tester for adhesives, labels, and tapes, and top load compression tester for pipes and packaging. True UTMs can perform all of these and more. They are great multi-purpose instruments for any QC or R&D laboratory. The following are only a few common uses for UTMs: Tensile testing – One of the most common applications for UTM, a tensile test measure how strong a material is, how long it can stretch, and how stiff it is as the material is pulled apart until breaking point. Compression testing – Compr

Importance of Ultrasonic Pulse Velocity Test in The Construction Industry

Image
In the construction industry, it is important to ensure that structures are built properly using the highest-quality materials and construction methods. Hence, certain tests must be conducted to ensure the quality of certain materials. The ultrasonic pulse velocity test is one of the most essential tests designed to determine the quality of natural rock and concrete. This testing method is preferred because it is non-destructive and it is conducted on site, saving builders a lot of time and money. In an ultrasonic pulse velocity test, the quality and strength of rock or concrete is determined by measuring the velocity of the ultrasonic pulse, which passes through the natural rock formation or concrete structure. The test is conducted using specialised equipment that generates a pulse of ultrasonic wave and measuring the time it takes for that pulse to go through the concrete. A high velocity indicates that the material is continuous and high-quality, and a slower velocity may
