An aim of the work is to develop the models and the methods of calculation of residual stresses and microstructure of cylinders under multilayered growing and following thermomechanical loading. Theoretical investigations were carried out on the base of mechanics of growing nonhomogeneous viscoplastic bodies. Iterative and time step methods as well as finite element method were used for numerical modeling. Mathematical modeling of thermomechanical processes under multilayered deposition and subsequent loading of cylinders was carried out. It was found that the high plastic underlay reduced residual stresses and deformations in basic cylinder up to 50%, and in outside deposed layer up to 20%. Regime of cyclic plasticity under intensive mechanical tension appears, and it's necessary to select the material with greater cyclic yield limit to raise resistance to low-cycle fatigue failure. The results obtained can be used to select materials and surfacing technologies of rolls and punches to raise theirs resource. Product Description popup.authors Баняс М.В. Гололобов В.І.
