Theory This timely book presents cutting-edge developments by experts in the field on the rapidly developing and scientifically challenging area of full-field measurement techniques used in solid mechanics - including photoelasticity, grid methods, deflectometry, holography, speckle interferometry and digital image correlation. The evaluation of strains and the use of the measurements in subsequent parameter identification techniques to determine material properties are also presented.Since parametric identification techniques require a close coupling of theoretical models and experimental mISTEEngineering mathematicsMeasurementEngineering mathematics.Measurement.530.41Grediac Michel520707Hild F(Francois)520708MiAaPQMiAaPQMiAaPQBOOK9911019978703321Full-Field measurements and identification in solid mechanics834548UNINA
