This report contains a state-of-the-art summary of past and current research activities in the application of fracture mechanics methodologies to cracking and fracture of concrete as well as contains recommendations of a fracture model to determine the fracture process in concrete. Despite known problems, it is recommended that linear elastic fracture mechanics provides a suitable model. A detailed testing procedure and data evaluation are given using a three-point-loaded cracked beam specimen. Keywords: Fracture mechanics, Test methods, LEFM(Linear Elastic Fracture Mechanics), Crack propagation, Reinforced Concrete.
