Concrete Fracture Models and Applications

Contrasts the limitations of traditional Li1near Elastic Fracture Mechanics (LEFM) with more appropriate nonlinear fracture models, such as the cohesive crack model and the crack band model, necessary for accurately capturing concrete's softening behavior and the critical size effect. Significant attention is paid to specific contemporary methodologies, including the double-K and double-G fracture models, which provide efficient means to analyze crack initiation and unstable propagation in structural design. Furthermore, the material outlines common experimental procedures and specimen geometries, comparing the uses and advantages of the Three-Point Bending Test (TPBT), Compact Tension (CT) test, and the increasingly favored Wedge Splitting Test (WST). The document concludes with extensive acknowledgments, recognizing the large community of researchers who contributed to the development of these complex fracture criteria.You can listen and download our episodes for free on more than 10 different platforms:https://linktr.ee/civil_engineering_made_simpleProduced by:https://www.podcaistudio.com/
