What is Flow of a material refers to: and explain in detail?
The term flow, rather than creep, has generally been used in dentistry to describe the rheology of amorphous materials.
Creep is defined as the time-dependent plastic strain of a material under a static load or constant stress.
The creep or flow is measured as the percentage decrease in length that occurs under these testing conditions.
Key Concept: Flow of a material refers to continued change of the material under a given load.
