NTS has the ability atm test and analyze plastics, rubber and other polymer materials. To ensure materials and products perform accordingly, there are different types of mechanical testing they may undergo: If you cannot find the special services you are looking for here on our website, please contact us directly for more information.

The physical and mechanical testing of a product comprises a critical part of the product and development process.

To support your mechanical testing needs, NTS also offers a variety of chemical testing and analysis, including:. Fracture testing is commonly employed by companies to develop maintenance schedules and forecast the service life of parts.

Mechanical Testing Services | NTS

Mechanical testing employs a variety of strength tests that can determine the suitability of a material or component for the intended application. Data sheets for overmetals, plastics, ceramics, and composites.

It measures characteristics such as elasticity, tensile strength, elongation, hardness, facture toughness, impact resistance, stress fracture, and the fatigue limit. We use various types of polymer testing and analysis to identify base materials and additives, verify material hardness and tensile strength and assess product features.

We will provide a comprehensive root cause analysis report, which will list all findings from our investigation and ensure you have the answers you need to prevent a recurrence.

Tensile testing — This type of mechanical testing measures ast force required to pull an object — such as a rope, wire or beam — to the point that it breaks. NTS Mechanical Testing Laboratory Capabilities Mechanical testing can help you expand the boundaries of performance in your products and components. Other industries that can benefit from NTS mechanical testing and certifications services include: The test engineer loads the specimen between two plates, and then has a force applied to the specimen by moving the crossheads together.

The testing expert measures the impression length and uses the c621 along with the test load to calculate the hardness value. 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.

Multi – layer composite bearings. In sectors like aerospace, defense, medical devices and other industries, there is no room for error. Fatigue testing — Depending on the source, fatigue comprises between 50 and 90 percent of all mechanical failures.

Fabric bearings; Laboratory equipment. Our fatigue testing capabilities include axial, torsional, high-cycle, low-cycle, bending, rotating, shear, r621 load, and multiple degree of freedom.

Excessive inelastic deformation depends on the plastic properties of the material — ultimate tensile strength, strain hardening and hardness. One of the most common methods is called microindentation hardness testing or microhardness testing.

This failure may occur under load conditions that cause fatigue, ductile facture and creep. Subscribe to Premium Services Searches: Property Data This page displays only the text of a atm data sheet. With a global network, NTS can handle standard testing requests or customize a testing protocol to meet your needs.

NTS engineers work closely with our customers to understand their operational and commercial needs, which enable us to deliver the results and the customer satisfaction they expect every time. To ensure materials and products perform accordingly, there are different types of mechanical testing they may undergo:.

MatWeb is intended for personal, non-commercial use. This type of failure can also transpire under the loading condition of unstable equilibrium — bucking of a column or brittle fracture.

Mechanical testing can help you expand the boundaries of performance in your products and components. Information provided by Dalau. We can calibrate most gauges as well as measuring tools and electrical, temperature, torque, force, mass and humidity, masters and pressure instruments. We document all test results in detailed Certified Test Reports. We have a global reputation based on technical capabilities and service, integrity and the quality of our results.

The tensile strength is the maximum amount of tensile stress that the object can withstand before failure — an important concept in mechanical engineering, structural engineering and material science. Some Fluorinated Hydrocarbons refrigerants cause reversible swelling i. NTS can perform the necessary analysis and inspection.

We advise that you only use the original value or one of its raw conversions in your calculations to minimize rounding error. Stress raisers or defects in the material can further encourage the growth of the crack.

We also ask that you refer to MatWeb’s terms of use regarding this information. Tensile testing subjects a sample to uniaxial tension until it fails.

There are three primary reasons why a component can become dysfunctional: Applied physical force such as vibration, shock stresses, and strain can reveal the inelastic behavior of the material. Other industries that can benefit from NTS mechanical testing and certifications services include:.
