Abstract

The present study utilizes Acoustic Emission (AE) Testing to investigate the fracture process in 3D Printed-Ultra High-Performance Concrete (3DP-UHPC) beams under three-point bending. These 3D printed UHPC specimens are reinforced with micro steel fibers at a dosage of2% by volume and feature two distinct notch depths, 6 mm and 60 mm. During the testing process, AE is employed to evaluate the fracture process zone and transition ligament length (al) of the prisms. The Work of fracture method and the Boundary Effect method is employed to determine both Size-Dependent (Gf) and Size Independent Fracture energies (GF).
