摘要：
The current and residual deflections of sheet members during one- and two-layer build-up with three steels under different support conditions are analyzed. A mathematical model of the process is developed. It is based on the theory of built-up bodies, the unified model of viscoplastic flow, and continuous cooling transformation diagrams for microstructural transformations during cooling. The method of numerical modeling of the build-up process based on the finite-element approach is developed. A significant effect of microstructural transformations and support conditions on the residual deflection of surfaced sheet members is established. The correlation between the calculated and experimental data is satisfactory. The obtained results can be used to determine the parameters of the processes of surfacing sheet members.
