Abstract
Computer simulation based on finite element method was used to study the influence of the ratio of dimensions (radii and height) of cylindrical parts of the type of cylinders and bushings from dissimilar materials on the stress-strain state in the butt zone in diffusion welding, allowing for plastic deformations under the conditions of loading by compression and thermal cycling, and to establish the regularities of its formation.
 
 
Keywords: diffusion welding, dissimilar materials, stressstrain state, plastic deformation, cylinder-cylinder component, bushing-bushing component, relative radius, relative height, computer simulation, stagnation point
