In this paper experimental and computational results obtained by numerical simulation of uniaxial tension of 0.7 mm thick metal plate specimens are compared. The Digimat-FE (MSC) system was used for modelling, which in numerical calculations uses the finite element solver of the Marc (MSC) software package. It is shown that for specimens without coatings the found theoretical values of critical load correspond quite well to the points on the experimental diagrams, at which the dependence of load and displacement ceases to be linear. For coated specimens, the critical loads turn out to be considerably lower, and for their description, it is necessary to obtain a refined estimate taking into account the action of residual stresses.
Key words: Coatings / mechanical properties / modelling / strength / stresses
