Stress–Strain State of Sheet Elements During Oneand Two-Layer Buildup

The residual stress–strain state of sheet elements during one- and two-layer buildup with two steels under two boundary conditions is studied. The mathematical model of the process is based on the theory of built-up bodies, the unified Bodner–Partom viscoplastic flow model, and continuous cooling tr...

Description
Summary:The residual stress–strain state of sheet elements during one- and two-layer buildup with two steels under two boundary conditions is studied. The mathematical model of the process is based on the theory of built-up bodies, the unified Bodner–Partom viscoplastic flow model, and continuous cooling transformation diagrams. The buildup process is numerically modeled using the finite-element method. A significant effect of microstructural transformations and boundary conditions on the residual stress–strain state of built-up sheet elements is revealed. The models of plane strain and stress states are compared.
