The total fracture energy indicated improvements in fracture behavior of FGCM relative to full-depth plain concrete. The fracture behavior of FGCM depended on the position of the fiber-reinforced layer relative to the starter notch. The fracture parameters of both fiber-reinforced and plain concrete were embedded into a finite element-based ...

Fracture Model for Fiber Reinforced Concrete

Mar 01, 1983  Date: 3/1/1983. Abstract: A fracture model is developed to generate the entire crack growth resistance curve (R-curve) of fiber reinforced cementitious composites, including the steady state fracture energy. The crack growth mechanism in these materials is described in terms of three different zones: stress-free, pseudoplastic, and process.
