Prediction of Defects in the Structure of Non-Metallic Heterogeneous Materials
Abstract
Heterogeneous media can be represented as specially organized heterogeneous materials. The complex process of forming heterogeneous materials and media as systems is realized by gradually transitioning from one state to another. The presence of many one-time transformations of space-time structures causes the latter. When simulating damage such as cracks and fractures in products made of non-metallic heterogeneous materials, which consists of “assigning” the place of damage to the product at a specific moment in time, neither the method of random selection from the previously compiled list of “dangerous” places, nor the method of transfer to the object can be used, which is modeled, the results of field and operational tests of other products of a similar class or even other products of the same class. Therefore, it is proposed to use a combined method of obtaining a stream of quasi-random numbers, that is, a stream of random numbers that are “modulated” by information about defects in the structure of the material of the product, which was obtained because of field tests of the products or during their operation.
