Zusammenfassung:A method for monitoring stress on a wind turbine blade (14) during loading is disclosed. The method includes capturing multiple images (102) at respective locations of the blade. The method also includes measuring temperature (104) at the respective locations based upon captured images. The method further includes calculating stress (106) applied on the blade (14) at the respective locations based upon the measured temperature. The method further includes comparing the calculated stress with respective theoretical stress (108) in a finite element model to predict lifetime of the blade. The method also includes alerting an operator (110) in event that the calculated stress at one or more of the respective locations is above a predetermined limit.
