Utilization of holographic interferometry to determine the principal plane stresses in a shock-loaded photoelastic model
Abstract
The paper describes a method for the separate but simultaneous determination of isochromatic and isopachous fringes for plane stress problems under transient conditions. A holographic system using a Faraday cell and a two-pulse ruby laser is employed to obtain isopachous fringes. Isochromatic fringes are recorded in a circular-light polariscope with electrooptical shutter. The method is used to determine the principal stresses in a photoelastic disk subjected to radial impact.
