G ⇒Shear Modulus- Slope of the initial linear portion of the shear stress-strain diagram. G (Steel) ≈ 12 x 106psi G (Aluminum) ≈ 4 x 106psi Percent Elongation- The strain at fracture in tension, expressed as a percentage = ((final gage length - initial gage length)/ initial gage length) x 100. Percent elongation is a measure of ductility.

When steel is curved, it is important to keep the stress-strain curve ratio for mild steel in mind. Below is a stress-strain graph that reviews the properties of steel in detail. If tensile force is applied to a steel bar, it will have some elongation. If the force is small enough, the ratio of the stress and strain will remain proportional.

The formula that is used for the calculation of stress and strain are Where, σ = stress P = Load e = strain dL = extension produced in the rod L = original length A = cross section area We plot a graph between the stress and strain and a curve is obtained. This curve so obtained is called the stress strain curve or stress strain diagram.

STRESS-STRAIN DIAGRAM: The mechanical properties of a material are determined in the laboratory by performing test on the small specimens of the material. Most common material test is the Tension Test. In this test, loads are measured on the main dial of the machine while the elongations are measured with the help of extensometers.

In this experiment we will look at the stress-strain behavior of two types of steel that bound the range usually seen in civil engineering applications - from a very mild, hot rolled steel to a hard, cold rolled one. Principles The term steel is commonly used to denote a material that is principally iron (Fe), often in the 95% to 98% range.

As shown below in the stress strain curve. From the diagram one can see the different mark points on the curve. It is because, when a ductile material like mild steel is subjected to tensile test, then it passes various stages before fracture. These stages are; Proportional Limit Elastic Limit Yield Point Ultimate Stress Point Breaking Point
