Evaluation Approach of Rock Brittleness Index for Fracturing Acidizing Based on Energy Evolution Theory and Damage Constitutive Relation [PDF]
Lithosphere, 2021 AbstractAcidizing, as an essential approach for well stimulation of sandstone or carbonate reservoirs, greatly affects the brittleness of the rock mass. Therefore, it is of great significance to develop a scientific brittleness evaluation methodology for the acid-corroded rock.

Journal of Materials Research and Technology, 2023 The particle/matrix interface of metal matrix composites (MMCs) can give rise to extra strength and then affect the local deformation behavior. This strengthening effect originates from the plastic strain gradients due to the incompatibility of plastic deformation between the particle and matrix.

Damage evolution and fracture in terms of the theory of phase transition
Procedia Structural Integrity, 2019 Abstract The development of many fields of science proves the usefulness of the interdisciplinary approach to the phenomena under investigation, based on the physical analogy of the described processes and their general laws. So, it is known the similarity of the relations obtained by J. Gibbs and A.

Phase-field modelling of ductile fracture: a variational gradient-extended plasticity-damage theory and its micromorphic regularization [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2016 This work outlines a novel variational-based theory for the phase-field modelling of ductile fracture in elastic–plastic solids undergoing large strains. The phase-field approach regularizes sharp crack surfaces within a pure continuum setting by a specific gradient damage modelling.

Application of Percolation Theory to Rock Damage and Fracture
Key Engineering Materials, 2007 Rock is a kind of complex and high-disordered geological material, its damage and fracture process usually shows obvious criticality. In this paper, percolation theory is applied to analyze and describe this critical property. First, we discuss the critical fracture probability of rock through percolation and renormalization analysis, and present the ...

Damage and Fracture Analysis of Bolted Joints of Composite Materials Based on Peridynamic Theory
Polish Maritime Research, 2019 Abstract It is clear that the advantages of fibre glass-reinforced plastics surpass those of steel, but the failure analysis of composite structures is much more complex than that of isotropic materials as composite materials may fail in a variety of ways.
