The paper presents numerical calculations results of a sandwich specimen subjected to four-point bending. The sample was loaded with a bending moment of Mg = 16 Nm. The specimen was made of the following materials: upper beam M1 - structural steel S235JR, lower beam M2 - aluminum alloy AW-2017A, glued joints AJ - MULTIBOND-3670 adhesive. The purpose of the paper is to present the stress distribution in glued joints of the sandwich type sample under four-point bending. The variable value in the calculations was the glued joint shape of the side surface. As a result of calculations, reduced stress distributions in glued joints were determined, which showed that: the highest stress values σH-M occur in glued joint AJ with flat side surfaces at the contact with the upper beam M1 in its central (point GZ_2), on the glued joint inner surface AJ with flat side surfaces obtained a different stress distribution than on the outer surface of this joint.
