What is the advantages of the stress-strain diagram vs. the load elongation diagram for showing the results?

Answer 1

I agree with the other writer but wanted to add that stress and strain provide a means to sort out extraneous information and standardize or normalize the results. For example, you could be testing two different material such as a 6" concrete cylinder and a 1/8" steel bar. Presenting the results for load test on the same graph would make the concrete appear to be the strongest because it carries a larger load prior to failure. However, when using stress, the cross sectional area is included and the steel bolt would appear to have superior properties.

When graphing two samples, actual properties between them are easier to discern.

Answer 2

As one a lot the shape the stress gage shows circulation. The circulation is one axis of the diagram. the quantity of the burden is the different axis. So linear loading shows a as we communicate line wherein the stress is proportional to the burden. The shape recovers without harm. while the burden starts to bend the shape the line curves displaying "plastic" area and this means the shape is broken. If one will boost the burden to shape failure, you have got here upon the ultimate potential and the test ends.

Answer 3

Stress-Strain diagrams will show the elastic modulus, yield point, tensile strength, and failure strength of a material, with corresponding strain values.
