Stress Distribution in a Plate with a Holes Along the Diagonal Distribution Under Plane Biaxial Load

The object of the work is numerical analysis of the state of stress in the plate with holes made along its diagonal, which was subjected to a plane load. The plate was subjected to biaxial loading both in the direction of the y axis, i.e. P_y = +/-100 kN and the z axis, i.e. P_z = +/-100 kN. It was shown that the highest concentration of reduced stress occurred in a plate with two holes in the case of load in the form of pure shear (P_y = -100 kN, P_z = 100 kN). The pure shear load case proved to be the least favourable from the point of view of straining the plate with holes.
