Questions and Answers

What is fatigue in structures?

  • A type of failure that occurs under repeatedly applied loads (correct)
  • A type of failure that occurs under tensile loads
  • A type of failure that occurs under compressive loads
  • A type of failure that occurs under static loads

    • What is the purpose of a fatigue test?

  • To test the tensile strength of a material
  • To test the durability of a material under cyclic loading (correct)
  • To test the hardness of a material
  • To test the yield strength of a material

    • What type of cyclic loading is commonly used in testing?

  • Repeated stress cycle
  • Random stress cycle
  • Reversed stress cycle (correct)
  • Uniaxial stress cycle
