Contact us if you need any help with making your specimens. For sheet, plate and bar samples the sample preparation is straightforward, for other sample shapes, however, a great deal of machining may be required to produce a suitable tensile specimen. Tensile strength testing machine: Most tensile testing machines can operate in three modes: Constant-rate-of extension (CRE) Constant-rate-of traverse (CRT) Constant-rate-of-load (CRL). A hard testing machine produces the upper and lower yield point, but in a soft machine only the extension at constant load will be recorded. Shimadzu offers a range of first-class tensile testing instruments to meet R&D requirements in the development of safer and higher quality materials and products. Thus, GA-treated autologous pericardium has sufficient tensile strength for use in aortic valve reconstruction. It includes one module followed by a quiz. Significance and use. In a tensile test, a specimen is subjected to a controlled tension while measuring the applied load and the elongation of the specimen. Our machines are designed for use in Research departments and Quality Control departments to measure material’s strength and product performance. Materials testing, measurement of the characteristics and behaviour of such substances as metals, ceramics, or plastics under various conditions. The objective of the standards is to define and establish the test method in such a way, that even when different testing systems are used, the characteristic values to be determined remain reproducible and correct. High-speed tensile tests are performed using a high-speed testing machine. As early as 6,500 BC, potters were known to listen for audible sounds during the cooling of their ceramics, signifying structural ASTM D638 – Tensile Testing of Plastics. Purpose of tensile testing . Instron® offers a wide variety of tensile grips to suit your industry and testing application. Macroscale tensile testing of bulk materials is still one of the most common techniques for measuring their yield stress, elastic modulus, ultimate Sawyer’s 50 Ton Bend and Tensile Tester.
