EN The subject of the analytical and experimental studies therein is of two metal seven-layer beam-plate bands. The first beam-plate band is composed of a lengthwise trapezoidally corrugated main core and two crosswise trapezoidally corrugated cores of faces. The second beam-plate band is composed of a crosswise trapezoidally corrugated main core and two lengthwise trapezoidally corrugated cores offaces. The hypotheses of deformation of a normaI to the middle surface of the beams after bending are formulated. Equations of equilibrium are derived based on the theorem of minimum total potential energy. Three-point bending of the simply supported beams is theoretically and experimentally studied. The deflections of the two beams are determined with two methods, compared and presented.
