Influence of the Parameters of the Wave Profile of the Joint Boundary of Titanium-Aluminum Composite Layers on Stress Behavior

Abstract

Simulation by the finite element of tensile deformation of the titanium-aluminum composite D20 - AD1 - VT6S was carried out. The relative thickness of the soft layer AD1 was constant, and the parameters of the wave profile of the welded joint varied. An increase in the ratio of the amplitude to the step of the wave up to 0.5 leads to an increase in effort by 4-5%. It was compared with the force in a specimen with a flat boundary at comparable stretches. Plastic deformation is localized mainly near free surfaces.
