in this paper, the 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. Photoelasticity or polarization-optical method was used to research stresses of piezo-optical materials. The picture of interference fringe patterns in the model of a planetruss was obtained by the method of photoelasticity. Stresses were calculated with their help. The purpose of the work was compared with both methods. Fields of maximum tangent stresses were obtained in the sample plane using both methods.
