(a) 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.
(b) 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)?
(c) Briefly describe the process of yielding and give 3 examples of failure in a metal.
