Optimised methodologies for measurement of strain (D4, D11)

The diversity of optical techniques implies that the results can be dependent on the method used to acquire data. A set of draft standard guides has been generated for the following techniques: digital fringe pattern/image analysis, ESPI, grating interferometry, photoelasticity, image correlation, and thermoelasticity. The draft standard guides for photoelasticity and grating interferometry are based on existing guidelines and technical notes. They provide recommendations for best practice and optimised methodologies for the measurement of strain. They should lead to better quality of data being generated, so that engineering decisions are better informed. The target areas are all industries concerned with load-bearing components, from turbine blades to oilrigs.
