TWA 26

Full field optical stress and strain measurement

The TWA was established in the late 1990s and the aim was to bring together those concerned with the use of optical techniques for full field measurements of stress and strain in order to develop internationally accepted standards.

The scope of the TWA embraces all techniques for optically evaluating strain fields including:

  • Photoelasticity
  • Moiré methods
  • Laser speckle and interferometry methods
  • Image correlation techniques
  • Thermoelastic methods

A draft pre-standard was developed by a European consortium, SPOTS and reviewed by members of TWA 26.
