A Statistical Method for Inspection of Structure of Textile Materials.
The model of Markov random field is used for the characterization of structure of a textile material. From the digital image of the material, the parameters of the field are statistically estimated. The method comp...

On introduction of spatial material randomness into lattice-particle model of concrete fracture
notches loaded in three-point bending. We document how spatial randomness of material parameters allows a crack to initiate outside the shallow notch. The effect of notch depth and fluctuation rate of material
