The tensile properties of polymers are important for the design of plastic parts and the prediction of their performance under tension, particularly when used in structural applications. A tensile test is a fundamental mechanical test where a carefully prepared sample is loaded in a very controlled manner, while the measurement of the applied load and the elongation of the sample over a certain distance. Tensile tests are used to determine the modulus of elasticity, yield strength, elongation, proportional limit, surface reduction, tensile strength, yield strength, yield strength and other properties. The tensile properties are the best indication of the strength of a material. The force required to pull the specimen is determined together with the elongation at break. The elastic modulus is the ratio of stress to deformation below the proportional limit of the material. It is the most useful traction data, because the pieces must be designed in such a way that the stresses are below this value. The main product of a tensile test is a load curve versus elongation that then becomes a tension curve versus strain. Since stress Both engineering and engineering deformation are obtained by dividing load and elongation by constant values (specimen geometry information), the load-elongation curve will have the same shape as the stress-strain curves of engineering. The stress-strain curve refers to the stress and strain curves. Next, a typical engineering stress and strain curve is shown. The curves increase continuously until the fracture the true tension is based on the actual cross-sectional area of the sample. |  |
