Creep usually occurs as a result of thermal and physical stress overcoming the elasticity of the metal preventing it from returning to its original shape after the stress is removed.

What is scope creep in project management?

Scope creep refers to scope changes applied without processing them though the change control process. The role of the Project Manager is to ensure that Scope Creep does not happen in their project. As per the PMBoK guide, the Control Scope process is used to control the projects scope.


Difference between Stress relaxation test and creep test?

Creep - increase in deformation while load is cst Relaxation - decrease in load while deformation is cst.


When a project scope has a tendency to increase - known as?

Scope creep


What is creep in a piping system?

Creep in a piping system refers to the gradual and permanent deformation of materials under sustained high temperature and pressure over time. This phenomenon occurs when the pipe material, often metals, is subjected to stress, leading to elongation or changes in shape. Creep can compromise the integrity of the piping system, potentially resulting in leaks, failures, or structural damage if not properly managed. Regular monitoring and material selection are crucial to mitigate the effects of creep in high-temperature applications.


Metallurgical factors influencing various stages of creep?

Creep in materials is influenced by several metallurgical factors, including grain size, phase composition, and the presence of impurities or second-phase particles. Fine grain sizes typically enhance creep resistance due to the increased number of grain boundaries, which can impede dislocation movement. Additionally, the presence of alloying elements can strengthen the material through solid solution strengthening or precipitation hardening, while certain phases may enhance or detract from creep performance depending on their stability and ductility at elevated temperatures. Lastly, the material's temperature and stress conditions also play crucial roles in determining the creep behavior.
