View License Agreement A method of determining permanent strains by pre- and post-measurements of a grid of reference points or lines on a test specimen, a component, or a model under test is described. The characteristics of the grid at elevated temperature and some of the limitations are presented. The grid of points or lines is generated by a photographic and electrodeposition process. The determinations of the deformations can be accomplished by direct measurements of the model or photographs of the deformed grid. Measurements of grid lines after extended periods at elevated temperature gave reliable strain distributions. | ||
