TENSILE TEST REPORT


The materials to be investigated are Copper and Steel. One example of this could be to determine the Ultimate Tensile Stress of a material to be used for a shopping bag, to check it can hold enough weight. The machine will provide a threaded attachment to connect the specimens. The machine will exert a tensile force on the specimen causing it to extend. The force exerted to create each increment of extension is displayed on the machine along with the total extension. For this test the force exerted for every 0.

The Yield Stress for copper is not clearly represented by the graph as it shows the material yielding gradually, but it could be estimated to be at MPa by using a 0. The Yield Stress for steel occurs at MPa. The Elastic Modulus for the Steel and Copper samples as calculated from using the Yield Stresses stated previously are both The Copper elongated 6, tensile test lab report.

In a uniaxial fractured copper sample tensile test, this orientation represents the angle of principle shear stress and the surface demonstrates this principle Shear Stress caused the crystalline boundries to slip over each other before failure 3.

Both tensile test lab report these obeservations are characteristics of Ductile Fig. The Copper tensile test lab report also displayed a higher Toughness than the sample, which is represented by the larger area beneath the stress strain graph.

Despite being smaller than the Copper sample, the plastic region of the Steel sample is significantly large enough to be considered to have some ductile properties. B The surface of the fracture also possesed a cup and cone geometry at a lesser extent than the copper sample. Necking is a tensile test lab report of a ductile material. The difference between these results suggest that; a The yield stress for copper that was predicted using a proof stress may of given an inaccurate answer that is higher than the real value b The stress-stain results that were read from the machine were inacurate.

However, the difference between the two are very small, particuarly in the elastic region of the test, and could not cause such a large difference between the experimental and theoretial value of yield stress. This would mean the difference is more likely to be caused by a and that very little confidence can be placed on determining the yield stress with one run of an experiment and by detemining the yield stress using the graph, tensile test lab report. Because this value was more clearly defined on the graph than it was for copper and it was not derived using a proof tensile test lab report, it would be expected to be more accurate and could have a high confidence placed on it.

The values for the Modulus of Elasticity obtained experimentally are around one order of magnitude smaller than values stated in Engineering Materials 1 1 which quotes it to be GPa for mild Steel and GPa for Copper. Determining the Modulus of a material using a uni-axial tensile Stress experiment is generally regarded as being inaccurate and is instead commonly determined by measuring the natural frequency of a sample using an oscillation test 1, tensile test lab report.

The ultimate tensile stresses recorded are very close to the theoretical values, tensile test lab report, which are Mpa and MPa for copper and Carbon Steel Alloy 1The difference between the experimental and theoretical values for the Modulus suggests that in this case, very little confidence could be made with the results. In conclusion, copper can be regarded as a more Ductile material than steel with a higher Toughness, and Steel can be considered to have a higher Yield and Tensile Strength with an equal elastic Modulus.

Tensile Test Lab Report Name of student: Lecturer: Abstract This experiment was conducted so as compare the mechanical properties of aluminium and mild steel. The basics on the operation of universal testing machine were also learnt during this experiment. The Universal Testing Machine can be used to determine the tensile strengths of many. One material property that is widely used and recognized is the strength of a material. But what does the word "strength" mean? "Strength" can have many meanings, so let us take a closer look at what is meant by the strength of a material. We will look at a very easy experiment that provides lots of information about the strength or the mechanical behavior of a material, called the tensile test. convenient sample geometry for the tensile test is the "dogbone" geometry (Figure 1). In this test geometry, one end of σ = F A (1) i i o i = l (l) ε ∆ (2) σ = Eε (3) NOTE: In this paper the author is reporting values as (mean value) +/- (standard deviation) of the data.
