Universal tensile compression testing machines (UTMs) are important tools used in various industrial sectors. They are designed to assess the mechanical properties of materials and are commonly used for tests such as tension, compression, or bending. UTMs can be used for fundamental tests like tensile tests where a sample is subjected to a specific load until failure or deformation point as well as more complex applications. In this article, we will discuss the working principles, industrial applications, basic components, and selection criteria of universal tensile compression testing machines.
Universal Tensile Compression Testing Machines: Working Principle and Basic Components
Universal tensile compression testing machines are designed to evaluate the mechanical properties of a sample. These machines measure the load applied to a sample and the deformation the sample undergoes, determining the material's strength, ductility, and other mechanical properties. The main components of a UTM are:
-
Frame: The main structure where the sample is fixed and the load is applied.
-
Load Cell: A sensor that measures the load applied to the sample.
-
Moving Jaw: The part where the sample is fixed.
-
Sensors and Measurement Devices: Sensors that measure the sample's deformation and measurement devices that process this data.
UTMs are commonly used for tension, compression, and bending tests. Tensile tests measure the tensile force applied to a sample and are often used to determine the breaking strength of a material. Compression tests measure the compressive force applied to a sample and are often used to determine compressive strength. Bending tests measure the bending force applied to a sample and are often used to determine the flexibility of a material.
