Photoelastic strain gages

Application of photoelastic principle leads to development of new techniques for strain and stress analysis of structural parts
  • G. U. Oppel
Article

Abstract

New photoelastic strain gages are described which are self-contained and give an accurate direct indication of magnitudes and directions of principal stresses. Large numbers of gages may be observed simultaneously and critical areas of members may be readily located.

Various types of gages are applicable to high-termperature problems, dynamic measurements or direct photographic recording.
