| description | Stress state in a plane truss node was studied in two ways: numerically using the finite element method and experimentally using the photoelasticity method. The finite element method was used to calculate plane truss model. Photoelasticityor polarization-optical method was used to research stresses of piezo-optical materials. The picture of interference fringe patterns in the model of a plane truss was obtained by the method of photoelasticity. Stresses were calculated with their help. The purpose of the work was to compare both methods. Fields of maximum tangent stresses were obtained in the sample plane using both methods. This work is a continuation of [1]. So, we obtained picture of interference fringe patterns and isocline fields in the node of the farm model, using the photoelasticity method. The field of maximum tangent stresses in the truss node was obtained by the photoelasticity method. The stress fields in the truss node were obtained by the finite element method in the software package "SCAD". A comparative analysis of the numerical and physical experiments results was carried out and it was found that the nature of the stress distribution in both numerical and physical experiments coincides. |
