The effect of the diametrs and arrangement of titanium fibers in a fibrous composite with an aluminum matrix on the change in the stress-strain state upon indentation of a rigid spherical indenter by the Brinell method has been studied. The process of introducing a hard ball Ø 5 mm under a load of 1226 N was simulated in the SIMULIA / Abaqus software package. The distribution of plastic deformation in the cells near the surface of the deformed plate in the axial section has two maxima and almost zero near the center of the hole. The print becomes elliptical when the indenter is positioned over the axis of the titanium wire. The major axis of the ellipse is perpendicular to the axes of the wires. This is due to the restraint of aluminum deformation in this direction by titanium fibers.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
