www.mse.iastate.edushows a tensile testing machine, which looks similar to the one used in this lab. This test is a destructive method, in which a specimen of a standard shape and dimensions (prepared according to ASTM D 638tandard test method for tensile properties of : s plastics) is subjected to an axial load. As shown in Figure 6.1ng a typical tensile , duri

mtil.illinois.eduSep 09, 2002 · The Tensile Test This example uses data recorded during tensile testing on an Instron testing machine. The specimen is made of 6150 Steel. During the test, the load increases to a maximum value, then decreases. Eventually the specimen breaks. Information about the specimen and testing conditions are recorded in a header file.
