The strength of materials or simple Som is one of the important subjects, and it is almost the heart of the mechanical engineering field; it is also called the mechanics of strength. It mainly deals with the behaviour of materials when some external load is applied to them.
Some will explain the stresses, strains, breaks, fracture, and their different types that will be developed in a material. The behaviour of a material helps research, design, and decide whether it is suitable for a particular application.
The compressive strength test is done by compressive strength tester is a mechanical test measuring the maximum compressive load a material can bear before fracturing. A compression testing machine applies a steady load to compress the test component, which is typically a cube, prism, or cylinder, between two platens.
Rock, brick, cast iron, and concrete are all examples of brittle materials that can have high compressive strengths yet ultimately break. Crushing strength, measured by shattering a cube, is generally referred to as the cube strength, and it can reach values of around 3 tonnes per square inch for concrete, 10 tonnes per square inch for granite, and 25-60 tonnes per square inch for cast iron.
Some malleable metals, such as mild steel, have great compressive strengths; but the actual values are difficult to measure. When a load is applied to a malleable metal, it deforms elastically up to a certain point, and then plastic deformation occurs. Increasing loads may even completely flatten a test piece without any definite fracture occurring, so no value can be obtained for the compressive strength. In these cases, the custom of quoting tensile-strength values must be revised but safe, with compressive strength always greater.
The compression testing machine is utilized to determine a material’s resistance to compression. The sample is compressed until it either breaks or gets the desired degree of deformation. The construction, aerospace, and manufacturing industries are just a few that put compression testing devices to use to make sure their materials and products are up to snuff.
Compression testing equipment can be divided into two categories:
The most popular is hydraulic compression testing equipment. Hydraulic fluid compresses testing force. The piston forces the specimen with a pump and hydraulic fluid. Heavy-duty testing can generate large points from this equipment.
Servo-electric compression testers are newer and more advanced. Electric motors generate testing force more precisely and accurately than hydraulic equipment. Sustainable servo-electric machines use less energy than hydraulic ones. These machines are used to test materials that require precision force application.
Testing requirements, money, and space should be considered while choosing between hydraulic and servo-electric compression testing machines. Choosing a machine that fits the planned application and testing materials is crucial.
A material’s strength is its capacity to resist load without failure or plastic deformation. The power of materials is the force and deformation they cause. Elastic constants, mechanical characteristics, and deformation and cracking resistance determine a material’s strength. HEICO Dynamics Pvt. Ltd. provides complete assistance and machine knowledge.
