The Influence of Autocorrelation Length of Random Strength in Stochastic Discrete Simulations
Original language description
The contribution studies an influence of the autocorrelation length of a random field of local tensile strength and fracture energy on the fracture process zone in concrete beams. Experimentally obtained data on bending of concrete specimens of four different sizes with and without notch were simulated by discrete lattice-particle model enhanced by stochastic extension. The simulations reveal an interesting and clear dependence of the peak load on the autocorrelation length in terms of the mean value and also variability. For example, when the autocorrelation length in unnotched specimens equals roughly the fracture process zone size, the average specimen strength is significantly reduced.
