Consider the following statements regarding typical analysis of bolt failure :  1. 15% failure of bolt occur at the fillet under the head. 2. 50% failure of bolt occur at the end of threads on the shank. 3. 80% failure of bolt occur in the threads that are in contact with the nut. Which of the above statements is/are correct ?

Consider the following statements regarding typical analysis of bolt failure :  1. 15% failure of bolt occur at the fillet under the head. 2. 50% failure of bolt occur at the end of threads on the shank. 3. 80% failure of bolt occur in the threads that are in contact with the nut. Which of the above statements is/are correct ? Correct Answer 1 only

Explanation:

Bolt Failure Analysis: In this bolts are tested in different conditions and loadings and results are recorded for better understanding of failure.

According to bolt failure analysis:

  • 15% failures occur at the fillet under the head
  • 20% failures occur at the end of threads on the shank.
  • 65% failures occur in the threads that are in contact with the nut
