This classic creep law has been available in Abaqus for a very long time, yet I do not believe the Abaqus docs ever use the phrase "Bailey-Norton".  I use that phrase because it references quite easily a very particular form of a creep law. 

Norton is the stress to a power in 1929

Bailey added the time to a power part in 1935

What are the origins of the classic Bailey-Norton creep law?

Who is the Norton behind the Norton creep law?
