Tensile behavior of a laminated magnesium-aluminum composite with axial elliptical holes

Abstract

A 3D finite element simulation of the behavior of a prismatic sample of a magnesium-aluminum composite material AMg6-AD1-MA2-1 with an elliptical defect in the AD1 layer under axial tension was carried out, its strength and the change in the stress-strain state were determined when the thickness of the AD1 layer varied from 5 to 1, 25 mm. A change in the stress-strain state and strength during perforation transfer to the MA2-1 layer was revealed.
