One of the fundamental aspects in cohesive zone modeling is the definition of the traction-separation relationship across fracture surfaces, which approximates the nonlinear fracture process. Cohesive traction-separation relationships may be classified as either ...
ABSTRACT The effects of aggregate type, size, and content on the behavior of normal and high-strength concrete, and the relationships between compressive strength, flexural strength, and fracture energy are discussed. The concrete mixtures incorporate either ...
Continuing this policy, which is consistent with our stated objectives, the two September issues deal with the behavior of concrete and cementious materials during fracture initiation and propagation. We hope that the ensuing state-of-the-art review will yield
