... multiaxial cyclic loading often produces additional strain hardening, which is not usually observed under proportional loading conditions. The reason for the additional hardening is the interaction of slip planes, because many more slip planes are active during nonproportional loading due to the change...

... that chipping occurred once every 200 hammer weeks. Another interesting observation made by Burn was that the strain hardening of the striking face that occurs during the use of a hammer increased the hardness 1.5 to 2.5 points HRC ( Ref 2 ). A fact not mentioned earlier about Burn's field tests...

Option 2 FAC Option 2 FAC is recommended for materials with a high initial work-hardening rate, (e.g., strain-aging mild steels), or for materials with a discontinuous yield point, or when the complete material true stress-strain curve is known. The Option 2 FAC was developed...

... hardening exponents ( n ) for most structural alloys are typically in the range of 0.05 to 0.2, which translates to a RA in the range of 5 to 22% before necking instability is attained. Thus, few materials that are not cold worked would neck before 2% strain and would be considered brittle in this criterion...
