Badania elastooptyczne modeli płaskich z wykorzystaniem holografii

In the paper are shown the results of original experiments. They were carried out in order to obtain the isopachic fringe patterns on a plane ring subjected to two external forces acting along the vertical diameter. A method of holographic photoelasticity is applied. The experimental data obtained allowed the two principal stresses to be separated along the symmetry line. The conclusions are drawn and a comparison with the theoretical solution is made. The present state of knowledge in the field of holographic photoelasticity is reported.
