Abstract
AbstractIn this study, a repeated drop-weight test on a 50 mm thick four-side fixed UHPFRC plate was carried out. A high-speed 3D Digital Image Correlation technique (3D DIC) was employed to capture the full-field response of the plate during impact loading. The DIC results were validated against the measurements of physical accelerometer and strain sensors attached on the top surface of the plate. The DIC results in combination with a polynomial surface fitting method was used to obtain the mid-point deflection. Replicability of the plate’s dynamic response indicated that only negligible damages occurred in the plate due to repeated drops from 0.5 m. During the subsequent impact from 2.0 m, the overall performance was governed by flexure. Lastly, the plate failed with local failure and flexure after impacted from 3.0 m.KeywordsUHPFRC plateImpact behaviourFixed support3D digital image correlationFull-field deformation measurements
