Modelowe badania koncentracji naprężeń w węzłach ustrojów nośnych metodą pokryć optycznie czynnych

Results of the investigation of the stress concentrations in joints of structures using ,,Modeltech'' method are presented in the paper. The method consists in stress and design analysis by means of full scale models made of epoxy with aluminium powder. Photoelastic coatings methods is used to analyse the stress field. Distributions of the stress components are given in the form of the maps.
