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.
