Interpreting raw strain gauge output
Interpreting raw strain gauge output
(OP)
Let's say you have an axial foil strain gauge attached to a steel part, and the test load on the part (loaded far below yield) is cycled from zero to 100% three times while the strain gauge output is recorded. You can therefore plot the strain gauge output (raw microstrain versus percent load), which shows an apparent hysteresis. How is the zero shift typically calculated and interpreted? And how do you typically use or apply this to the raw output strain data to determine the actual maximum strain on the part?

i mean, between the loadings the test specimen is just sitting there completly unloaded, but the strain gauge is indicating a reasonably significant strain
