Influence of multilayer beams cross-section shape on stiffness under bending

The study offers a new mathematical model of a multilayer beam stiffness under bending in any direction determination as well as the evaluation of extreme values and the corresponding directions of neutral layers and coordinates of geometric and stiffness centers. The influence of beam cross-section formation trajectory function f (t) = tm shape index m and a variety of different shapes of cross-sections geometric and stiffness centers, neutral layers direction angle θmax and a maximum stiffness under bending Dmax on variation regularities is determined.
