Strength Properties of Nonlinear Material of Single Beams
Abstract
OF SINGLE BEAMS The paper presents the investigations of stress-strain state of beams made of nonlinear material subjected to tensile and compressive deformations. The suggested numerical method is based on linearization of the system of equations. Based on this method, a series of numerical experiments is carried out, the results of which show that the deformation properties of the material do not follow the classical Hooke's law. Thus, the physical nonlinearity and different resistance of the material lead to a substantial change in the structural tensile deformation when compared to linear calculations. The maximum difference in the load limit is 23,4 %, while in the rotation angles and deflections, its is respectively 14,83 and 15,9 %. This, non-linear properties and different resistance of the material should be taken into account in this structural analysis.
