Portland cement concrete is a relatively brittle material. As a
result, mechanical behavior of concrete, conventionally reinforced
concrete, prestressed concrete, and fiber reinforced concrete is
critically influenced by crack propagation. It is, thus, not
surprising that attempts are being made to apply the concepts of
fracture mechanics to quantify the resistance to cracking in
cementious composites. The field of fracture mechanics originated
in the 1920's with A. A. Griffith's work on fracture of brittle
materials such as glass. Its most significant applications,
however, have been for controlling brittle fracture and fatigue
failure of metallic structures such as pressure vessels, airplanes,
ships and pipe lines. Considerable development has occurred in the
last twenty years in modifying Griffith's ideas or in proposing new
concepts to account for the ductility typical of metals. As a
result of these efforts, standard testing techniques have been
available to obtain fracture parameters for metals, and design
based on these parameters are included in relevant specifications.
Many attempts have been made, in the last two decades or so, to
apply the fracture mechanics concepts to cement, mortar, con crete
and reinforced concrete. So far, these attempts have not led to a
unique set of material parameters which can quantify the resistance
of these cementitious composites to fracture. No standard testing
methods and a generally accepted theoretical analysis are
established for concrete as they are for metals."
