Abstract
Modelling phenomena of structural mechanics requires the knowledge of mechanical parameters of the utilized material. Moulding of the material during the manufacturing process, e.g. drawing pipes, may alter the material properties slightly. In comparison to classical destructive measurement methods, which involve samples of specific shapes, or classical ultrasonic testing, requiring a minimum material thickness, the proposed method based on laser vibrometry and guided ultrasonic enables a simultaneous estimation of the elastic constants and the wall thickness of a pipe.
