tensile testing report
The report should describe the test you did and the results obtained, in a way that will make it useful to you as a reminder of what you did and how to do it. Interpretation of the test is more than interpretation of the results, but a critical examination of what the results show and of how reliably the test shows that would be one way to demonstrate understanding.
During this laboratory exercise, each group will do a regular tensile test on a different material. Students can choose the material which they want to test, from a few different options. They need to determine the following material properties from the measured data: Young Modulus, Poisson’s ratio, yield strength, and tensile strength, and plot the engineering stress-strain curve for the report. An extensometer will be used for measuring the longitudinal extension, and a strain gauge for the lateral contraction. The laboratory experiment includes the gluing of the strain gauge to the specimen.
Before the test, familiarise yourself with the relevant parts of the standard for tensile testing of metallic materials: SFS-EN ISO 6892 or ASTM E8M. Mixed in with their promotion of their own solutions you may find useful summaries of these standards by searching for the company name and the standard. For non-commercial use by staff and students, Aalto University Library provides access to Finnish Standards Association publications through their web portal SFS Online, if you access it through Aalto University Library.
