Influence of Autocorrelation Length in Random Lattice-Particle Model
Original language description
The main objective of the paper is to describe the role of autocorrelation length of random strength field in lattice-particle model (Cusatis et al. [1, 2]). The original formulation of the lattice-particle model is extended with a random field used formodeling of spatial variability of tensile strength and fracture energy of inter-particle connections [3, 4]. The paper presents lattice-particle models of experimentally tested concrete specimens. The experimental data [5] summarize a series of three point bent concrete specimens of four different sizes with and without notch. The simulations reveal an interesting and clear dependence of the peak load on the autocorrelation length. Apart from the effect of the autocorrelation length on variability of the peak load, we show that the mean value of the peak load of unnotched specimens exhibit a significant decrease when the autocorrelation length is about equal to the size of the fracture process zone.
