The article discusses about numerical methods and physics experiment for studying stress fields caused by defined load on beam. Examined the behavior of material under various modes load at individual types of beams. The results are compared, and then the right conclusions are drawn, that it is possible to verify the physical experiment and numerical calculation. For physical experiment was used transmission photoelasticimetry.
