OBJECTIVE :

Tension test is carried out; to obtain the stress-strain diagram, to determine the tensile properties and hence to get valuable information about the mechanical behavior and the engineering performance of the material…

INTRODUCTION:

A tensile test, also known as a tension test, tests a material’s strength. It's a mechanical test where a pulling force is applied to a material from both sides until the sample changes its shape or breaks. It's is a common and important test that provides a variety of information about the material being tested, including the elongation, yield point, tensile strength, and ultimate strength of the material. Our experiment was performed on (Mild Steel and Brass) also have to prove that it is Mild Steel by *Young Modules Equation*.

Also, it’s a sample of material describes how it reacts when tension is applied to it. By measuring the changes in the material as tension is applied, engineers can determine a variety of things about the material, which is helpful in determining whether the material is a suitable choice for the application they have in mind. Tensile testing systems use a number of different units of measurements. The SI (International Systems of Units), recommends the use of either (Pa) Pascal or Newton’s per square meter for describing tensile strength.

THEORY:

A tensile load is applied to the specimen until it fractures. During the test, the load required to make a certain elongation on the material is recorded. A load elongation curve is plotted by an x-y recorder, so that the tensile behavior of the material can be obtained. An engineering stress-strain curve can be constructed from this load-elongation curve by making the required calculations. Then the mechanical parameters that we search for can be found by studying on this curve.

    Out of the three materials tested, the steel 1045 exhibited the most elastic properties, with it being able to deform elastically for a greater amount of stress than for the other specimens, as indicated by its stress-strain curve as shown in figure 1, and further supported by it having the highest modulus of elasticity of all three specimens, as shown in table 2. The mild steel specimen had the second greatest modulus of elasticity, and the aluminium specimen had the lowest modulus of…

    The foundation of Materials Science lies in characterization of a material’s properties. Among those properties the greatest interest lies in the strength of materials, being the most basic requirement for any kind of construction. This lab aims first to describe the strength of 1045 annealed and cold-rolled steel, 2024-T4 aluminum, and cast iron through tensile testing. This includes characterization of yield strengths, modulus of elasticity, ultimate tensile strength, and fracture strength for each material. An emphasis is placed on elastic-plastic deformation in terms of ductility and how temperature and fatigue can affect this transition. Elastic and plastic…

    Young's modulus, also known as the tensile modulus, is a measure of the stiffness of an elastic material and is a quantity used to characterize materials. Young's modulus is named after Thomas Young, the 19th century British scientist. It is a very important concept that categorizes metals on basis of their elasticity. In the last lab, we were asked to find out the Young Modulus of two wires: Copper and Steel. I worked on Copper wire. My hypothesis on the report was that “The Young Modulus of a wire is directly proportional to the extension possible by the object.” Which means, the more a wire stretches from its original position the more will be its Young Modulus. It is because, F = -kx, and –k should be that constant.…
