From: Patterns of longitudinal and tangential maturation stresses in Eucalyptus nitens plantation trees
Step by step procedure for measurement of released maturation strains along tangential (T) and longitudinal (L) directions. a Remove the bark, b peel the cambium, c paste the gauges along the grain (detailed in d), d connect to data-logger and initialize, e release along T with two grooves on both sides of each gauge and f release along L by sawing above and below each gauge
