Note (General): The plastic strain range of stress-strain curve during fatigue process was measured for an annealed and a rolled steel for general structure SS400. It was found that variation in plastic strain range Δε_p was expressed using movable dislocation density ρ and Burgers vector b. The movable dislocation density was estimated from the plastic strain range and was expressed as a function of the number of stress cycles n by the following equations using a model based on the multiplication and annihilation process of dislocations. Δε_p=√<ρ>b,ρ=1/(β/α+1/ρ_0e<-an>+<βk>/αn). It was concluded that the calculation using this equation corresponds well with plastic strain range.
