In Andrade's analysis of creep, the two components that together form the creep curve are
Show Hint
Creep has transient + steady-state components in Andrade’s model.
Updated On: Jun 29, 2026
- Elastic strain and plastic flow
- Dislocation creep and diffusion creep
- Primary creep and tertiary creep
- Transient creep and constant-rate viscous creep
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Andrade’s theory describes creep deformation as a combination of transient and steady-state viscous flow.
Step 1: Creep curve components.
Creep deformation consists of:
• transient (primary) creep → decreasing rate
• steady-state (secondary) creep → constant rate viscous flow
Step 2: Andrade’s interpretation.
Andrade modeled creep as:
• anelastic transient deformation
• viscous flow component Final Answer: \[ \boxed{\text{Transient creep and constant-rate viscous creep}} \]
