Question

Which of the following is/are true regarding stress rupture?

(a) The stress required to cause a rupture in a predetermined time at a constant temperature

(b) It is important in short-term high-temperature applications

(c) Stress rupture is an important mechanical property for gas turbine or rocket engines

(d) The stress required to cause a rupture in short-term high-temperature applications at a predetermined time is known as stress rupture and it is an important mechanical property for gas turbines and rocket engines

I have been asked this question by my college director while I was bunking the class.

My question comes from High Temperature Materials topic in chapter High Temperature Corrosion of Corrosion Engineering

Answer 1

Correct option is (d) The stress required to cause a rupture in short-term high-temperature applications at a predetermined time is known as stress rupture and it is an important mechanical property for gas turbines and rocket engines

The best I can explain: Stress rupture is defined as the amount of stress that is required to cause a rupture in short-term high-temperature applications at a predetermined time. It is an important mechanical property for gas turbines and rocket engines.
