Metoda skośnego prześwietlania do analizy płaskiego stanu naprężenia przy wykorzystaniu jedynie pola izochrom

Marek Sikoń

A photoelastic method to solve the plane stress problem on the basis of isochromatic patterns obtained by means of observation of the model in 3 different directions is suggested. The theoretical analysis was performed and the effective formulas for calculating stresses were obtained. To confirm the theoretical analysis an experiment on a circular disk loaded with 2 concentrated forces along the diameter was conducted. The results of the experiment confirmed theoretical calculations. Possibilities of the development of this method are shown.
