Acoustic Emission and Numerical Analysis of Pine Beams Retrofitted with FRP and Poplar Wood

Acoustic Emission and Numerical Analysis of Pine Beams Retrofitted with FRP and Poplar Wood

Acoustic emission (AE) released by pine beams retrofitted with fiber reinforced plastic (FRP) and poplar planks in bending is analyzed. Basalt fabric (FB), carbon fabric (FC), and carbon pultruded laminate (LC) have been used as FRP. Experimental results and AE behavior are discussed based on an ela...
