Modeling statistical size effect in quasibrittle structures by computattional stochastic fracture mechanics
Original language description
The paper presents theoretical and computational study and model of possible sources of size effects in concrete structures acting both separately and together. A particular motivation is the interplay of several identified scaling stemming from the material, boundary conditions and geometry. Methods of stochastic nonlinear fracture mechanics are used to model the well published results of direct tensile tests of dog-bone specimens with rotating boundary conditions. The computational approach representsa marriage of advanced computational nonlinear fracture mechanics with simulation techniques for random fields representing spatially varying material properties. Using a numerical example, it is documented how different dources of size effects detrimental to strength can interact and result in relatively complex quasibrittle failure processes.
