Measuring mechanical stress in living tissues - Nature

Web(1 + ε) = σ (1 + ε ) (5.17) where σ and ε are the engineering stress and strain values at a particular load. True stress and true strain values are particularly necessary when one is working with large plastic deformations such as large deformation of structures or in metal forming processes. WebStrain gauges were used to measure the strain on the plate, and the results showed that stress concentration occurred around the hole, leading to increased strain. On the other hand, differences between actual and theoretical values were caused by several reasons, showing how critical accuracy is in the experiment 1.
