Damage mechanisms where deterioration rates are immeasurable or unknown are
A) Stress corrosion cracking
B) Hydrogen induced cracking
C) Thinning
D) All of the above
E) Both A and B

Question

Quizplus · Accepted Answer

Stress corrosion cracking and hydrogen induced cracking are both damage mechanisms where the deterioration rates can be difficult to measure accurately, if at all. Thinning, on the other hand, is a degradation mechanism that can often be measured or monitored over time, making it less likely to be included in this category. Therefore, options A and B are correct, and option C is not. The correct answer is choice letter E.
