Evaluation of crack resistance based on the numerical modeling of the plane strained state

  • Published:
Materials Science Aims and scope

We propose a method for the nondestructive evaluation of the ultimate strength and fracture toughness K Ic of structural steels based on the high-precision data on strains and stresses obtained as a result of the improved numerical solution of the problem of plane strained state in the nonstationary elastoplastic formulation. The developed method satisfactorily describes the degradation of strength of structural materials intended for long-term operation at high or low temperatures in aggressive media or under the action of radiation, in particular, of 15Kh2NMFA, 10GN2MFA, and 2Cr–Ni–Mo–V reactor steels.
