TENSILE TESTING OF METALS
Aim:
The aim of the experiment is to determine the behaviour in tension of metallic materials. Depending on the material and the production method used to produce the test piece various kinds of responses are possible in extension to the applied load.
Introduction:
The tensile test provides an estimate of the strength and ductility of metal materials. The test is carried out on a small sample of material according to BS 18 Methods for tensile testing of metals. It should be noted that the results obtained can only be used as a guide to the performance of the material as a whole.
The following experiment was designed to determine some of the mechanical characteristics of various materials. These included the stress strain characteristics, such as Young's Modulus, yield strength and tensile strength. I will use the theory of material science to help explain the properties of our samples, and predict the outcome of the results and then compare this to what actually happened once the test is complete. I will take into account how carbon has affected the properties of steel and as has alloying to Aluminum.
