Enter the creep strain and the strain due to permanent stress into the Calculator. The calculator will evaluate the Creep Factor. 

Creep Factor Formula

CF = CS / SPS

Variables:

  • CF is the Creep Factor ()
  • CS is the creep strain
  • SPS is the strain due to permanent stress

To calculate the Creep Factor, divide the cree strain by the strain due to permanent stress.

How to Calculate Creep Factor?

The following steps outline how to calculate the Creep Factor.


  1. First, determine the creep strain. 
  2. Next, determine the strain due to permanent stress. 
  3. Next, gather the formula from above = CF = CS / SPS.
  4. Finally, calculate the Creep Factor.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

creep strain = 1500

strain due to permanent stress = 3000

FAQ

What is creep strain?
Creep strain refers to the deformation that materials undergo when subjected to a constant stress over a prolonged period. It’s a measure of how a material stretches or compresses under such conditions.

Why is calculating the Creep Factor important?
Calculating the Creep Factor is crucial in engineering and materials science because it helps predict the long-term deformation behavior of materials under stress. This is important for ensuring the durability and structural integrity of constructions and components.

Can the Creep Factor change over time?
Yes, the Creep Factor can change over time as the material undergoes more strain or if the conditions affecting the material, such as temperature or the magnitude of the applied stress, change. Continuous monitoring and recalculations may be necessary for accurate predictions.

Are there materials that do not exhibit creep?
All materials can exhibit creep under the right conditions of stress, temperature, and time. However, the rate and extent of creep can vary widely between materials. Some materials, like ceramics at room temperature, exhibit minimal creep, while others, like metals at high temperatures, can show significant creep.
