Mixed-model fracture is a prevailing phenomena in
concrete. At present, there are two main approaches in describing the fracture
behavior of concrete structures: One using stress intensity factor(SIF) as
the main fracture parameter, and the other being energy based.
Theoretically, these two methods should be consistent with each other.
The basic assumptions, standards and application ranges of
different fracture criteria are discussed. Furthermore, by
comparing results in tests, the
merits and demerits of different fracture criteria are discussed.
