According to the elastic failure theory which of the following statement(s) is/are correct? i. Failure in ductile materials is specified through yielding ii. Failure in brittle materials is specified through yielding iii. Failure in ductile materials is specified through fracture iv. Failure in brittle materials is specified through slipping
- AOnly (i)Correct
- B(i) and (ii)
- C(ii) and (iii)
- D(iii) and (iv)
Solution
Concept
Failure criteria
Step-by-step solution
1. Ductile materials fail by yielding. 2. Brittle materials fail by fracture.
Explanation
Only statement (i) is correct.
Why the other options are wrong
Other statements reverse the modes.
Shortcut
Ductile = yield; brittle = fracture.
Correct answer: A) Only (i)
