Figure 6: Calculation of true bending strain and measurement of weld pool temperature as a function of time.
From: Initiation and growth kinetics of solidification cracking during welding of steel

The resultant true strain curves at different strain rates and weld pool temperature history profile are used to quantify kinetics for damage initiation. The three markers indicate damage initiation strain calculated from the image sequence of in situ radiography at 8 s−1, 7 s−1 and 6 s−1 strain rate respectively.
