2. Analysis of the macroscopic behavior of martensitic steels at low loads

2.1 Cyclic deformation

The influence of the total strain amplitude applied has been studied in detail. The evolution of the stress drop can be plotted as a function of the number of cycles or cumulative plastic strain, equal to :

p=2NΔEvp

with :

N
 : 
number of cycles,
ΔE vp
 : 
the viscoplastic strain variation per...
