Foreword -- Preface -- List of Symbols and Abbreviations -- Introduction to Fracture Mechanics of Concrete -- Fracture Mechanics of Concrete – State-of-the-Art Review -- Fracture Behavior of Concrete using Cohesive Crack and Size Effect Models -- Crack Propagation Study using Double-K and Double-G Fracture Parameters -- Fracture Properties of Concrete based on the KRcurve Associated with Cohesive Stress Distribution -- Comparison of Fracture Parameters of Concrete using Nonlinear Fracture Models -- Appendix. Subject index.

Cementitious materials, rocks and fibre-reinforced composites commonly termed as quasibrittle, need a different fracture mechanics approach to model the crack propagation study because of the presence of significant size of fracture process zone ahead of the crack-tip. Recent studies show that concrete structures manifest three important stages in fracture process: crack initiation, stable crack propagation and unstable fracture or failure. Fracture Mechanics concept can better explain the above various stages including the concepts of ductility, size-effect, strain softening and post-cracking behavior of concrete and concrete structures.
