DEIVANATHAN R PREPARED BY: SHUBHAM KUMAR 12BME0146 SANDEEP KUMAR 12BME0491 ABHISHEK CHANDRAKAR 12BME0444 ABHINAV PATHAK 12BME0514 GAURAV GOYAL 12BME0086 AMITESH GAVEL 12BME0081
  2. 2. OBJECTIVES  To find and study the mechanical properties of materials and compare them by plotting the graph. Materials are -:  Brass  Mild steel  Aluminium
  3. 3.  Tensile strength->it is the maximum stress that a material can withstand while being stretched or pulled before failing or breaking. Tensile strength is the opposite of compressive strength.  Hardness ->it is a measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied. TYPES OF MECHANICAL PROPERTIES
  4. 4. CONT…  Ductility-> It is a solid material's ability to deform under tensile stress; this is often characterized by the material's ability to be streched.  Young's modulus-> It is defined as the ratio of the stress along an axis over the strain along that axis in the range of stress in which Hooke's law holds.
  5. 5. WORK PLAN  We will take these three materials, measure their mechanical properties using respective instrument as mentioned above.  We will plot the graph of properties these materials and do their compare their strength.  We will study the importance of each material and its importance in different fields manufacturing industries.

  9. 9. Tensile Test  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. The major parameters that describe the stress-strain  Curve obtained during the tension test are the I. Tensile strength (UTS) II. Yield strength III. Elastic modulus (E) IV. Toughness
  10. 10. PROPERTIES OBTAINED FROM TENSILE TEST  Young's Modulus: This is the slope of the linear portion of the stress-strain curve, it is usually specific to each material; a constant, known value.  Ultimate Tensile Strength: This is the highest value of stress on the stress-strain curve.  Ductility: It is the measure of the plastic deformation that has been sustained at fracture point. 10

  25. 25. 7.1 WHY DO WE COMPARE? 28 •To develop a standard, with which to compare others. •Allows trends to be identified and plotted. •To determine how are results might effect real life applications. •It allows us to predict what might happen in later experiments (e.g. What a combination of the materials might exhibit).
  26. 26. OUR RESULTS
  27. 27. 7.3 INTERPRETATION It is clear from the graph that....  The three metals behaved in very different ways.  Aluminium was the softest, more ductile of the three samples.  Brass behaved in a less ductile manner.  Order of toughness as obtained from graph: Mild Steel < Aluminium < Brass  The ultimate tensile strength (UTS) varied greatly between metals. 30
