Abstract
The paper is devoted to expanded-tapered sandwich beam under three-point bending. The analytical model of the beam based on the broken-line hypothesis (zig-zag theory) is developed. The maximum deflection of the beam with consideration of the shear effect is analytically determined. Moreover, a numerical FEM model (SolidWorks) of the beam is formulated. The maximum deflections of example beams with the use of two methods are calculated and compared. The results are specified in Tables.
