NTS has a nationwide network of professional material testing labs with material analysis expertise and experience that encompass a variety of industries, such as automotive, defense, telecommunications, and consumer services. To support your mechanical testing needs, NTS also offers a variety of chemical testing and analysis, including:. We also provide customized test procedures to meet customer specifications and help them meet performance goals. Available Properties Density, BS Mechanical testing employs a variety of strength tests that can determine the suitability of a material or component for the intended application.

Property Data This page displays zstm the text of a material data sheet. We can perform this test at various levels of the manufacturing process, including standard testing methods during testing of the raw material.

Tensile testing — This type of mechanical testing measures the force required to pull an object — such as a rope, wire or beam — to the point that it breaks. Fatigue testing aatm a testing method performed on parts and products to determine the localized and progressive structural damage that happens when a material is subjected to cyclical loading.

Users requiring more precise data for scientific or engineering calculations can click on the property value to see the original value as well as raw conversions to equivalent units. NTS mechanical testing expertise gives you the confidence you need on future performance and safety. Fracture testing is commonly employed by companies to develop maintenance schedules and forecast the service life of parts.

The test engineer loads the specimen between two plates, and then has a force applied to the specimen by moving the crossheads together. Fracture mechanics helps to determine the severity of a flaw and recognize when it becomes a problem.

Flat gaskets are used to seal flanges in pipelines. We can verify performance properties to determine functionality and to predict performance over time.

Fabric bearings; Laboratory equipment. NTS can perform 6d21 testing as an independent analysis or in combination with environmental stimulation, including: To ensure materials and products perform accordingly, there are different types of mechanical testing they may undergo: Excessive elastic deformation may occur under loading conditions of stable equilibrium like the excessive deflection of a steel beam.

The scope of mechanical testing can range from characterization of material properties to certification of the integrity of final products and safety. With a global network, NTS can handle standard testing requests or customize a testing protocol to meet your needs. Compression testing — Refers to a technique that determines the behavior of materials under a compressive load to determine elastic limit, proportional limit, yield point, yield strength and compressive strength if applicable.

Tensile testing subjects a sample to uniaxial tension until it fails. We can calibrate most gauges as well as measuring tools and electrical, temperature, torque, force, mass and humidity, masters and pressure instruments. We also ask that you refer to MatWeb’s terms of use regarding this information. Login to see your most recently viewed materials here. Some of the different areas in which we can perform test services include: Other industries that can benefit from NTS mechanical testing and certifications services include:.

The method uses a precision diamond indenter that can be impressed in a range of loads into material.

NTS can perform the necessary analysis and inspection. Our significant intellectual and physical assets ensure we can manage and support the changing needs of our customers — just as we have been doing for the last 50 years and look forward to doing for 50 more.

Excessive inelastic deformation depends on the plastic properties of the material — ultimate tensile strength, strain hardening and hardness. Stress raisers or defects in the material can further encourage the growth of the crack.

NTS has the ability to test and analyze plastics, rubber and other polymer materials. We can also work with you to develop a custom testing regimen for general quality assurance or for pre-compliance with ISO or other standards. If you cannot find the special services you are looking for here on our website, please contact us directly for more information. This failure may occur under load conditions that cause fatigue, ductile facture and creep.

NTS works with defense and governmental agencies to provide testing and certification for Tier I and Tier II suppliers for numerous industrial, commercial and military applications, including tensile testing, fracture mechanics, fastener testing, composite testing and fatigue testing.

One of the most common methods is called microindentation hardness testing or microhardness testing. Please contact us at webmaster matweb. Mechanical testing provides valuable information regarding the suitability of a material or component for its intended application. We appreciate your input. Many companies utilize the results of tensile tests, and along with failure theories, to predict failure of components that are prone to more generalized stress conditions.

The physical and mechanical testing of a product comprises a critical part of the product and development process. We advise that you only use the original value or one of its raw conversions in your calculations to d6211 rounding error. NTS tensile testing capabilities include axial tensile testing, weld tensile testing, wedge tensile testing, castings tensile testing, elevated temperature tensile and tensile testing for machined specimens. Subscribe to Premium Services Searches: We have d6211 global reputation based on technical capabilities and service, integrity and the quality of our results.

Applied physical force such as vibration, shock stresses, and strain can reveal the inelastic behavior of the material. Data sheets for over f621, metals, plastics, ceramics, and composites. There are three primary reasons why a component can become dysfunctional: To ensure materials and products perform accordingly, there are different types of mechanical testing they may undergo:.
