Achieving reliable results in tensile testing of plastics

Sep 14, 2017 · Improper determination of test specimen dimensions can result in a relatively high number of stress value errors. When a specimen is subjected to a tensile load, the measurement error is reflected linearly by the stress result. When a specimen is subjected to a flexure load, the specimen thickness measurement error has a quadratic effect.

Tensile Test Experiment Materials Science and

The basic idea of a tensile test is to place a sample of a material between two fixtures called "grips" which clamp the material. The material has known dimensions, like length and cross-sectional area. We then begin to apply weight to the material gripped at one end while the other end is fixed. Tensile test - tec-scienceSetup. The tensile test is one of the most important testing methods for characterizing or obtaining material parameters. In the tensile test, for example, it is determined which load a material can withstand until it begins to deform plastically (yield strength) or under which maximum load the material breaks (tensile strength).The tensile test can also be used to determine the elongation at
