During the laboratory a Tinius Olsen Tension Test equipment was used‚ and the test samples were from low and high carbon steel and timber with grains parallel and perpendicular to the load. Test equipment and materials The test equipment used during the laboratory is one of the Benchtop Materials Testing Machines made by Tinius Olsen. This machine can test different types of

ABSTARCT: Tensile tests are fundamental for understanding properties of different materials‚ and how they will behave under load. These properties can be used for design and analysis of engineering structures‚ and for developing new Materials that better suit a specified use. This lab tested two materials mild steel and cast iron. The data from each test was used to determine valuable material properties such as ultimate tensile strength‚ modulus of elasticity‚ and yield strength. Other calculated

History Polyethylene was first synthesized by the German chemist Hans von Pechmann who prepared it by accident in 1898 while heating diazomethane. When his colleagues Eugen Bamberger and Friedrich Tschirner characterized the white‚ waxy‚ substance that he had created they recognized that it contained long -CH2- chains and termed it polymethylene. The first industrially practical polyethylene synthesis was discovered (again by accident) in 1933 by Eric Fawcett and Reginald Gibson at the ICI

ever know that the term “Styrofoam” is a proper noun? It is the trademark of Dow Chemical Company for their invention of a closed-cell extruded polystyrene foam ‚ or Styrofoam‚ used for craft and construction applications‚ packaging‚ and thermal insulation. However‚ in some countries‚ the term styrofoam is used as a generic term for expanded polystyrene expanded foam. Styrofoam has a number of purposes in the human world. It is because of its distinctive characteristics‚ properties and features

Tensile Testing Of Metallic Materials 概要： Tensile testing of metallic materials is specified according to European EN 10002 standard. In this article the terms‚ definitions and designation for tensile test made at ambient temperature is described. The test involves straining a test piece in tension‚ generally to fracture‚ for the purpose of determining mechanical properties. Tensile testing of metallic materials is specified according to European EN 10002 standard. This standards consists of five

Tensile Strength Report | Materials in Practice CP4088/CP8011 | By Clinton Chang | Synopsis This experiment is to find out the tensile strength of different plastic materials. The four plastic materials used are General Purpose Polystyrene (GPPS)‚ High Impact Polystyrene (HIPS)‚ High Density Polyethylene (HDPE) and Polypropylene (PP). By using three samples from each plastic material type‚ we are able to obtain the mean tensile strength‚ mean tensile modulus and mean yield strength of each

Yield Strength As we apply a low level of stress to a material; the material initially exhibits elastic deformation. In this region the strain that develops is completely and quickly recovered when the applied stress is removed. However‚ as we continue to increase the applied stress the material begins to exhibit both elastic and plastic deformation. The critical stress value needed to initiate plastic deformation is defined as the elastic limit of the material. In metallic materials‚ this is usually
