Review on Fractal Analysis of Porous Metal Materials

open access: yesJournal of Chemistry, 2015
Porous metal materials are multifunctional lightweight materials and have been used widely in industry. The structural and functional characters of porous metal materials depend on the pore structure which can be described effectively by the fractal ...

Relationship Between Pore-Size Distribution and 1D Compressibility of Different Reconstituted Clays Based on Fractal Theory

open access: yesFractal and Fractional
This paper first examines the evolution of pore-size distribution (PSD) in four types of reconstituted clays during one-dimensional (1D) compression, utilising mercury intrusion porosimetry.

Fractal Analysis of Particle Distribution and Scale Effect in a Soil–Rock Mixture

open access: yesFractal and Fractional, 2022
A soil–rock mixture (SRM) is a type of heterogeneous geomaterial, and the particle distribution of SRM can be described by fractal theory. At present, it is difficult to quantify the fractal dimension of a particle size distribution and understand the ...

Automatic Picking Method for the First Arrival Time of Microseismic Signals Based on Fractal Theory and Feature Fusion

open access: yesFractal and Fractional
Microseismic signals induced by mining activities often have low signal-to-noise ratios, and traditional picking methods are easily affected by noise, making accurate identification of P-wave arrivals difficult.

Hodge-de Rham theory on fractal graphs and fractals

open access: yesCommunications on Pure and Applied Analysis, 2014
We present a new approach to the theory of k-forms on self-similar fractals. We work out the details for two examples, the standard Sierpinski gasket and the 3-dimensional Sierpinski gasket, but the method is expected to be effective for many PCF fractals and also infinitely ramified fractals such as the Sierpinski carpet.

Fractal-Based Research Approach for Lignocellulose-to-Ethanol Conversion

open access: yesBioResources, 2014
The microstructure of porous lignocellulose has irregularity, which represents self-similarity within the scope of a certain scale, and the conversion process of lignocellulose to bioethanol is complex.

Research progress in design and characterization of porous materials based on fractal theory

open access: yesCailiao gongcheng
The complexity of cavities, randomness of pore distribution, and multi-scale of pore size in porous materials make it difficult to quantitatively characterize pore microstructure.
