- Based on the photo-elastic method, four groups of different ratio light elastic-plastic material were prepared by changing the epoxy resin, the firming agent, the plasticizer mass ratio; and the light elastic-plasticity material stress-strain curve and its elastic modulus E and Poisson's ratio were obtained through the stretch experiment. The light elastic-plastic rail models were made by 1:5, and the computation analyzes stress distribution of the rail head of the heavy rail and carried on the static examination. The stress stripe chart change rule of the light elastic-plasticity material during load and unload process was observed.
