Abstract

A pseudoelastic force balance equation for a single martensitic plate is introduced and proposed as the mechanical analog of the thermoelastic force balance introduced by Olson and Cohen. The difference between these two balances is the presence of a mechanical work term in the pseudoelastic case, in addition to the chemical term common to both. The chemical term was both experimentally determined and independently estimated for the complex case of pseudotwinning and pseudoelastic behavior in Fe0.81Be0.19, and the upper limits of these two values are found to be in agreement. Finally, analysis of the pseudoelastic force balance for the Fe0.81Be0.19 case shows that the transformation strain energy contributes substantially to the force balance and cannot be ignored.
