Abstract
The method of computer modelling based on FEM was used to study the stress-strain state of cylindrical parts in diffusion bonding. It is shown that the complex stressed state with a non-uniform distribution of stresses is formed over the surface of a bond in joining even simple parts from dissimilar materials. It is established that thermal cycling is indicated to localise plastic strains within the bond zone in joints with different values of linear temperature expansion coefficient.
Keywords: diffusion bonding, similar and dissimilar materials, stress-strain state, computer modelling
