Every day, people rely on structures to support their weight and maintain their shape under tension. A mandatory approval for materials and products used in these structures is tensile testing to ensure their suitability for specific loads. Tensile testing laboratories are needed to evaluate a wide range of material properties at both low and high temperatures and observe the effects on tensile and yield strength.
During a tensile test, the load is increased until the test sample finally fails. Tensile strength is the maximum load divided by the original cross-sectional area of the test sample. Yield strength refers to the stress at which plastic deformation or flow begins.
There are three criteria that define the onset of flow. These properties are the elastic limit, the proportional limit, and the yield strength. The sample is clamped by the top and bottom handles of the tensile testing machine. During the tensile test, the handles are released at a constant rate to pull and elongate the sample.
The force acting on the sample and its displacement are continuously monitored and recorded in a stress-strain curve until failure. After the tensile specimen breaks, technicians calculate the dimensions, tensile strength, yield strength, and ductility. The total length of the broken sample is compared to the length of the sample before the test to determine the elongation.
Additionally, the original cross-sectional measurements are compared to the final cross-section to determine the reduction in area.
High temperature tensile testing is a sub-method for evaluating the behavior of materials under a combination of heat and stress. When performing tensile testing at elevated temperatures, samples are placed in an oven on a test carousel that can handle up to three samples at a time. Our computer-controlled system heats and immerses the samples to the required temperature. The samples are then loaded into a test frame, where state-of-the-art strain gauges measure the strain of the sample as the load increases. Similarly, cryogenic tensile testing on round and flat samples is an option for evaluating the properties of materials cooled to -320°F in liquid nitrogen (LN2). See it tested in action! We use optical non-contact extensometers on our 60K tensile testers to give you more testing options.
They are the perfect instrument for non-contact measurement of axial strain or displacement. Their high resolution and ISO 0.5 / ASTM B-1 accuracy class make them suitable for non-contact measurement of a wide range of strain values, including the very small strains required to measure the elastic modulus of metals. Non-contact extensometers are also ideal for testing brittle, porous and additively manufactured materials.
