Assignment:
Question 1. Sketch the typical stress-strain curve for a metal and a ceramic. Using the sketch, indicate the following properties; elastic and plastic regions, yield points, Ultimate Tensile Strength (UTS), strain energy and fracture toughness.
Question 2. A cylindrical specimen of a titanium alloy with a Young's modulus of 107 GPa has an original length of 250mm and a diameter of 3.8mm. It will experience only elastic deformation when a tensile force of 2000 N is applied. How much will it elongate (stretch)?
Question 3. Briefly describe the process of yielding and give 3 examples of failure in a metal.
Provide complete and step by step solution for the question and show calculations and use formulas.
