Calibration of constitutive models of steel beams subject to local buckling by using Digital Image Correlation

Abstract : It is proposed to identify the behavior of steel beams prior to and after the inception of local buckling by using Digital Image Correlation. Full field measurements are used to evaluate kinematic and static fields for determining constitutive laws. It enables for the detection of local buckling inception and the evaluation of the postbuckled behavior. Constitutive models are tuned by using measured Euler-Bernoulli kinematics.
