- Abstract
- Equations for describing the bending deformation of laminated beams-wall of regular patterns with varying degrees of accuracy were obtained. Of them as special cases the equations for the classical theory of Bernoulli and both variants of the theory of Timoshenko are followed.. A simplified version of a refined theory developed for statically determinate beams. On the example of study of bending behavior of hinge supported beam it is shown that for the nonlinear-elastic behavior of materials of its composition the classical theory and both Tymoshenko theories don't guarantee obtaining of reliable results within 5 % -engineering accuracy. It is requires the use refined theories which allows to calculate the boundary layers that occur in phase materials in the neighborhood of supported section of beam.
