TL;DR: In this article, a comprehensive methodology for the analysis of residual stresses due to welding and quenching processes is detailed using the finite element method, where nonlinearities due to the variation of material properties and heat transfer coefficients with temperature and those due to inclusion of a radiation boundary condition and solid phase transformation effects are considered in the thermal and thermo-elasto-plastic formulations.

TL;DR: In this article, the analysis of cylindrical-to-spherical shell multipass weld joint is carried out by finite element simulation to obtain the residual stresses and the extent of heat affected region from the weld.

TL;DR: In this paper, the authors examined the feasibility of theoretically analysing the residual stresses in the parallel heat welding process, and compared with the results obtained by previous authors by using finite element analysis.

TL;DR: A mathematical model was developed for computing the metallurgical phase transformations and residual stresses in centrifugal casting of bi-metal grinding rolls used for coal pulverizing as mentioned in this paper, considering variation of thermo-mechanical properties of material with temperature, effects of phase changes and metallurgy phase transformations Rolls idealized as having infinite cylindrical geometry and actual finite conical geometry are analyzed for cases of air and water jet cooling of the centrifuging die.
