| Abstract: | A finite element method has been employed to calculate the effect of prestrain,particle
size,volume fraction and yield strength ratio of the constituent phases on the Bauschinger
Effect(BE)and residual phase stresses for ferrite-martensite two-phase steels.The rela-
tionship between the BE parameters and residual phase stresses is given,and the
foundamentals of inelastic unloading and the effect of reverse deformation on the BE and
residual phase stresses are also discussed.Some of the calculated data are compared with
experimental results and the good agreement between them is found. |
