3D scanning as an effective tool for controlling the dimensions of test specimens
Original language description
3D laser scanning is a powerfull tool that digitally captures the shape of physical objects using a laser light crosses. In this work, the 3D laser scanning technology is used for the 3D shape capture of specially designed specimens. These specimens previously made of fine-grained cement-based composite of the nominal dimensions 40 × 40 × 160 mm with inclusion in the shape of prisms with nominal dimensions of 8 × 8 × 40 mm were provided with an initial central edge notch and tested in the three-point bending configuration. The aim of this paper is to study the macrostructure of fracture surfaces via 3D scanning technology, measure the area of ligament, verify the designed notch depth and evaluate the fracture toughness and specific fracture energy based on the measured dimensions. The results indicate that the measured notch depth is lower than the designed one thus the differences between fracture toughness calculated for designed notch depth and for the measured one is approximately 10 %. In addition, the fracture toughness is overestimated when considering the design values.
