Numerical analysis of sandwich beam with corrugated core under three-point bending

The strength problem of sandwich beam with corrugated core under three-point bending is presented.The beam are made of steel and formed by three mutually orthogonal corrugated layers. The finite element analysis (FEA) of the sandwich beam is performedwith the use of the FEM system - ABAQUS. The relationship between the applied load and deflection in three-point bending is considered.

Experimental three-point bending of sandwich beam with corrugated core

Presented paper isdevoted to experimental test of three-point bending of sandwich beam. The core of the beam was formed by three mutually orthogonal corrugated layers.

Three-point bending of seven layers beams - theoretical and experimental studies

Abstract 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 of faces. The hypotheses of deformation of a normal 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.
