Magnetic Or Optical Surface Layer Would Indicate StrainIn proposed method of obtaining information on strain at surface of material specimen, magnetic coat (like that on magnetic tape) or optical coat (like that on compact disk) applied to all or part of surface monitored. Coating layer and associated measuring equipment, taken together, constitute system called "material strain monitor" (MSM). MSM important in research in materials and mechanics; in particular, expected to compete strongly with systems based on image-analysis and laser techniques now being developed to obtain information on strain fields.
