摘要

One of the features of direct laser metal deposition (DLMD) method is presence of high residual stress in produced parts. The information about residual stress distribution is critically important for the competent organization of production processes in additive manufacturing. To study residual stress distribution in large thin-walled parts produced by DLMD, two model samples were manufactured. Small thickness of the samples allowed using the calculation technique that does not require measurement of the lattice parameter of stress-free sample. It is shown that stress distribution in thin-walled plate built on a rigid substrate considerably differs from distribution in plate built on a flexible substrate.
