摘要
This paper presents a comparative study of laminated plate modal rotation field measured with two different Sheoragraphy techniques. A double pulse and stroboscopic continues LASER illumination is used to capture the full-field of the first ten modal rotation field of a carbon fibre reinforced epoxy rectangular plate in free-free condition. The plate is excited acoustically at their natural frequencies, which were identified by experimental modal analysis. It is shown that both techniques allow measuring the modal rotation field, but the Shearography technique based on stroboscopic continues LASER illumination is more robust to the experimental noise and presents higher dynamic range.
