Tensile load on bar5/2/2024 ![]() Tensile test based on the tensile test data is calculated by using the below formula: The cross-sectional area (at the center of the test specimen) of the test specimen is required to calculate the value of stress or tensile strength. ![]() The value of stress (force/ unit area, denoted by σ) either Yield Stress or Tensile Stress, and the strain (percentage elongation, denoted by ε) is obtained by the tensile test result. Tensile Test Calculationsĭuring the test, the value of applied load (F) & change in total length ((∆L) of the test specimen is measured continuously. Since the tensile test has a special significance in the assessment of base materials and in the examination of welded joints, the experimental conditions must be defined as precisely as possible, so that different testing lab always reports clean and comparable results. Here, a tensile test coupon is generally loaded to the breaking point and the required tensile force is recorded. room temperature or elevated temperature) as specified in the test standards or code. The purpose of the Tensile Test is to determine one or more strength (e.g tensile strength & Yield strength) and deformation (percentage elongation or reduction in area) properties in compliance with certain conditions (e.g. ![]() A gradually increasing tensile load is applied to the specimen and the resultant extension (or strain) of the specimen is observed. The machine consists essentially of two parts: the straining or pulling device and an arrangement to measure and register the load on a dial. Tensile Test ProcedureĪ tensile specimen of standard dimensions machined from the metal is inserted in a tensile testing machine (shown in the below figure). The tensile Testing method measures the force required to break a metallic, composite, or plastic specimen and the extent to which the specimen stretches or elongates to that breaking point. Tensile testing or Tensile Test is also known as Tension Test is a Destructive Test method and the most common type of mechanical test.Ī tensile test is used to determine the yield point or yield strength, tensile strength or ultimate tensile stress, and percentage elongation of a metal. What is the TENSILE TESTING or TENSILE TEST? The most important parameters measured in the test are the ultimate tensile strength, yield strength, and elongation at break. The results are typically recorded in a stress-strain diagram. The tensile test procedure involves attaching the sample to the testing machine and applying force until the material fractures.
