## Diagram of strain

Yield point in a stress strain diagram is defined as the point at which the material starts to deform plastically. After the yield point is passed there is permanent deformation develops in the

material and which is not reversible. There are two yield points and it is upper yield point and lower yield point. Axial Deformation · Beam Deflections OverviewDuctile materialsBrittle materialsThe

relationship between the stress and strain that a particular material displays is known as that particular material's stress–strain curve. It is unique for each material and is found by recording the amount of deformation at distinct intervals of tensile or compressive loading. These curves reveal many of the properties of a material. Stress–strain curves of various materials vary widely, and different tensile tests conducted on the same material yield different results, dependingSee more on en.wikipedia.org · Text under CC-BY-SA license Strain(∈)= Change in length (L i) / Original

Stress and Strain Curves or Diagram: Stress and strain curve is a behavior of the material when it is subjected to load. The strain diagram is determined by lab experiments. The main purpose is to get a property called “modulus of elasticity” where it is used in designing processes to determine a suitable material for a specific structure. G ⇒ Shear Modulus - Slope of the initial

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

diagram From the data of a tension test, it is possible to compute various values of the stress and corresponding strain in the specimen and then plot the result. The resulting curve is called the stress-strain diagram. Stress-Strain Diagrams, Material Properties, and Shear Stress and Strain. In this section, we will develop stress-strain diagrams, discuss material properties, and look more in depth at shear stress and strain. Module 9: Tension Test and Stress-Strain Diagram 10:00.
