What is creep in materials?

Problem Statement

What is creep in materials?

Step-by-Step Explanation

Creep is slow permanent deformation under sustained load, often at high temperature.

1. Identify what the question is asking. In Materials Science, this usually means naming the known quantities, the unknown quantity, and the concept that connects them.
2. Write the relevant definition, rule, or relationship before substituting numbers or manipulating symbols.
3. Work one step at a time and keep units, signs, and restrictions visible.
4. Check whether the answer makes sense in the original context.

Final Answer

Creep is slow permanent deformation under sustained load, often at high temperature. The reliable strategy is to start from the definition, apply the correct rule carefully, and then interpret the result in plain language.
