Strength of Materials Aims and scope

Abstract

We perform the numerical and experimental investigation of the physicomechanical properties of structurally inhomogeneous welded materials. For austenitic steels, we deduce computational relations for the distributions of the fields of elastoplastic strains in welded joints with regard for the anisotropy of the mechanical properties of the material and the kinetics of residual welding stresses. We also study functional dependences of the strain intensity factors for surface semielliptic cracks of different orientations in the material and various loading modes.
