Compression testing equipment is used to evaluate the mechanical properties of materials under compressive forces. When the material is loaded in compression, the specimen tends to get shorter in the direction of loading. The load and unload rate can be controlled and certain safety measures should be taken while using compression testing equipment. There are five basic types of stress-strain diagrams that can be created by controlling different parameters (extension rate, temperature, and moisture).
Uses of Compression Testing Machine
Materials can be compressed in different ways and at different rates, so there’s a need for a variety of tools and methods for assessing their mechanical properties. The most common method uses a universal testing fixture that’s designed for testing both single-sided Vs double-sided materials (for instance: steel plates vs concrete slabs). This type of fixture is called an “all-purpose” test machine because it can accommodate any type of specimen with equal ease; however, there are also specialized fixtures available for specific applications such as concrete slabs or reinforced concrete beams—and even more specific types like stainless steel rebars!
Types of testing compression testing machines used for compression tests
There are many types of testing machines used for compression tests such as tensile tester, universal tester, horizontal compression testing machine, and more.
Tensile testers are used to measure the force required to stretch or pull apart two materials under tension (tension being defined as being in force). The test results can be used to determine whether a material will break when subjected to a certain amount of stress. Universal testers are similar to tensile testers but also measure stress levels at various points along the length of a specimen instead of just at one point. Horizontal testing machines allow you to perform your own tests by placing samples on them so that you can check various things about them like their dimensions or shape changes under different stresses
Common test
The most common test is the loading and unloading of the specimen. In this test, a specimen is loaded in compression and tends to get shorter in the direction of loading. Specimens are compressed to a specific strain level that can be measured by measuring their length before and after loading into the testing machine.
Accessories used in Compression Testing Equipment
Compression testing equipment includes accessories such as upper and lower platens, support bars, extensometer, grips, and more.
- Upper Platen: The upper platen is used to apply the load on a specimen. It can be made of steel or aluminum with a thickness depending on its purpose.
- Lower Platen: The lower plate is placed below the specimen during compression testing to transfer stress into it by means of static pressure applied between them (see figure below).
- Support Bars: Support bars are used for supporting specimens during testing so that they do not move outwards under pressure from other parts of your machine such as cams etc. In addition, there may be other purposes such as guiding beams through holes in a frame allowing easier access when connecting cables, etc.
Certain safety measures should be taken while using compression testing equipment.
- Wear safety glasses.
- Use the right tools.
- Be careful of sharp edges and don’t over-tighten bolts or screws, as they can damage your equipment and lead to serious injury or death. Also, don’t use tools that are not designed for the job; this includes using a hammer on a drill driver (which should only be used with drills), as well as using an electrician’s screwdriver when working on electrical outlets because it won’t fit properly into their holes in order to tighten them down completely without damaging either item!
Find the mechanical properties of materials under compressive forces.
Compression testing equipment is used to find the mechanical properties of materials under compressive forces. Compression testing equipment includes accessories such as upper and lower platens, support bars, extensometer, grips, and more.
The most common method used in compression testing is the drop method. In this test procedure, a sample is placed on a rigid base with an upper platen that can be adjusted to any height above it by means of knobs or valves. This allows you to control the amount of pressure applied to your material (and thus its stress intensity factor) over time during your tests so that you can get consistent results every time without having any guesswork involved!
Once you have chosen which type(s) of material(s) you want to be tested—whether they’re solid or not—you’ll need some sort of support system underneath them so they don’t fall off when loaded down by whatever weighting mechanism needs applying here at this point.”
Conclusion
Compression testing equipment is used to find the mechanical properties of materials under compressive forces. Compression testing machines are very useful in the industrial field because they provide a lot of information about the material being tested. It can help make decisions regarding issues such as how strong it is and what type of materials should be used in its products. The tension force will cause any material to shrink or expand depending on whether they have been loaded with enough weight.
