The concept of microsimulation of processes of joining dissimilar materials by plastic deformation

Introduction. Bond strength between dissimilar materials is the most important characteristic of laminated composites, which determines success its development for industrial use. In order to develop theory joining by plastic deformation, it proposed perform computer simulation joint deformation representative volumes on a microscale and compare parameters stress-strain state with previously presented theoretical mechanism. The aim this work analyze under establish location onset fracture surface oxide films. To achieve aim, following tasks are formulated: 1) study profiles be bonded deformation; 2) simulate finite element method (FE) contact surfaces microscale; 3) stages verify Research methodology. three-dimensional topography roughness was carried out Veeco Wyko NT1100 Optical Profiling System. Deform-3D FE package chosen as main research tool. Aluminum alloys AMg3 D16 were study. Results discussion. work, simulating layers performed, an analysis after various types processing out, studied compared Based results comparison, adequacy mechanism assessed, practical difficulties noted. Microscale made possible flow in near-surface materials, well identify areas probable films and, consequently, primary bonding materials.
