Tensile Testing of Metals is a destructive test process that provides information about the tensile strength, yield strength and ductility of the material. Laboratory Testing Inc., near Philadelphia, PA in the USA, performs the tensile test in accordance with industry standards and specifications, including ASTM tensile test methods. This process is also known as a tensile strength test or tension test.
Tensile Test Capabilities
ASTM D638 is performed by applying a tensile force to a sample specimen and measuring various properties of the specimen under stress. It is conducted on a universal testing machine (also called a tensile testing machine) at tensile rates ranging from 1 to 500 mm/min until the specimen fails (yields or breaks). Though ASTM D638 measures many different tensile. Note that in general, the testing equipment and methods are given in ASTM E8. However, there are certain exceptions to ASTM E8 practices in the testing of steel, and these are covered in the methods below. Procedure A: Tension Test. Measure and record the specimen dimensions. ADMET provides dies conforming to particular testing standards. Sample preparation is essential and usually specific. One example is ASTM D638, which explains five different specimen dimensions that have to be selected based on the characteristics of the material that needs to be tested.

Tension tests provide information on the strength and ductility of materials under uniaxial tensile stresses. This information may be.

The Tensile Test Process
Material strength testing, using the tensile or tension test method, involves applying an ever-increasing load to a test sample up to the point of failure. The process creates a stress/strain curve showing how the material reacts throughout the tensile test. The data generated during tensile testing is used to determine mechanical properties of materials and provides the following quantitative measurements:
Tensile strength,also known as Ultimate Tensile Strength (UTS), is the maximum tensile stress carried by the specimen, defined as the maximum load divided by the original cross-sectional area of the test sample.
Yield strength is the stress at which time permanent (plastic) deformation or yielding is observed to begin.
Ductility measurements are typically elongation, defined as the strain at, or after, the point of fracture, and reduction of area after the fracture of the test sample.
The test sample is securely held by top and bottom grips attached to the tensile or universal testing machine. During the tension test, the grips are moved apart at a constant rate to pull and stretch the specimen. The force on the specimen and its displacement is continuously monitored and plotted on a stress-strain curve until failure.

The test specimen is put back together to measure the final length, then this measurement is compared to the pre-test or original length to obtain elongation. The original cross section measurement is also compared to the final cross section to obtain reduction in area. Torrent turnitin software download.
Elevated Temperature Tensile Testing is a proven method of evaluating the behavior of materials under a combination of heat and tension. When performing an elevated temperature tensile test, the specimen is placed inside a furnace on our test carousel, which is capable of processing up to three specimens at a time. Our computer-controlled system heats the specimen to the required temperature, then allows it to soak. Next, the specimen is loaded into the test frame, where an extensometer in the latest design measures the strain on the specimen as the load is increased. Watch how the test is performed.
