[HTML][HTML] Discrete mechanical models of concrete fracture
Discrete models of solids have been motivated, in large part, by the discontinuous and
heterogeneous nature of material structure and its breakdown under loading. The …

A review on fracture propagation in concrete: Models, methods, and benchmark tests
F Mukhtar, A El-Tohfa - Engineering Fracture Mechanics, 2023 - Elsevier
Rigorous characterization of fracture evolution in quasi-brittle materials–such as concrete–
requires computationally intensive and, mostly, complex approaches. However, the …

Lattice element models and their peculiarities
This paper presents the lattice element models, as a class of discrete models, in which the
structural solid is represented as an assembly of one-dimensional elements. This idea …

[HTML][HTML] Acoustic emission and artificial intelligence procedure for crack source localization
The acoustic emission (AE) technique is one of the most widely used in the field of structural
monitoring. Its popularity mainly stems from the fact that it belongs to the category of non …

An examination of the size effect in quasi-brittle materials using a bond-based peridynamic model
This paper examines the size effect in quasi-brittle materials using a three-dimensional bond-
based peridynamic model. This is the first time that the capability of a peridynamic model to …

Fracture process zone characteristics and identification of the micro-fracture phases in recycled concrete
Normal and recycled aggregate concrete differ significantly in their fracture characteristics.
The cracking in recycled concrete initiates earlier; the fracture length is generally larger and …

[HTML][HTML] Experimental characterization and numerical modelling of fracture processes in granite
Failure in brittle rock happens because micro-cracks in the crystal structure coalesce and
form a localized fracture. The propagation of the fracture is in turn strongly influenced by …

Discrete modeling of concrete failure and size-effect
Size-effect in concrete and other quasi-brittle materials defines the relation between the
nominal strength and structural size when material fractures. The main cause of size-effect is …
