Abstract By use of a computer program, the finite element method has been employed to calculated the effect of particle size, matrix and volume fraction of phases on the stress and strain distributions in 12CrMo ferrite-martensite steel. In particular, the distributions of hydrostatic stress and maximum shear stress in each phase are given. The microscopic fracture mechanism revealed by these stress distributions coincides with experimental observations.
