COMPARATIVE ANALYSIS OF MODELS OF BENDING DEFORMATION OF REINFORCED WALLS-BEAMS OF NONLINEAR ELASTIC MATERIALS
The study obtained the ratios for describing of bending deformation of reinforced walls-beams with different accuracy, from which the classical Tymoshenko theory and both Bernoulli theory are follow as particular cases. On the example of study of mechanical 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 theory don''t guarantee obtaining of reliable results within 5%-engineering accuracy. It is requires the use refined theories with accounting edge effects in phase materials for conducting reliable calculations.
