Fractal Analysis of Deformation Curves of Fiber-Reinforced Fine-Grained Concretes Under Compression

Study of change in the deformation-strength properties of nanomodified fine-grained concretes over time

“…An insignificant number of papers are devoted to the problem of control over the deformation properties of finegrained concretes [17]. The main direction of studies, given in the work indicated, is the application of the micro-reinforcement of concrete using the fibers.…”

Applying the Fractal Analysis Methods for the Study of the Mechanisms of Deformation and Destruction of Polymeric Material Samples Affected by Tensile Stresses

“…The scientific papers provide various methods for determining the fractal dimension of the structure of real composite materials based on cement and polymeric binders [1, 5 -11]. In [11,12], the authors' team proposed a method for determining the fractal dimension of deformation curves based on the minimum coverage method, providing an integral quantitative estimate of the process of building composite destruction under compression, and enabling to determine the position of parametric points of the destruction curve. The proposed method is based on the use of data read using advanced test equipment making it possible to record changes in stresses and strains during the application of high-frequency mechanical loads to a sample [11,12].…”
