A numerical-analytical procedure for definition of residual stresses in a piecewise-homogeneous plates welded by a linear weld is developed; the elements of its software are formed. On the basis of developed mathematical models that consider thermal sensitivity of the material characteristics, temperature fields and stresses in the typical elements of design under welding are defined. In the Delphi medium 6.0 the program is realized for calculation of temperature fields caused by the surface weld sources with normally distributed power density in the plate-like and massive elements of design Product Description popup.authors popup.nrat_date 2020-04-02 Close
