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 …

One of the fundamental aspects in cohesive zone modeling is the definition of the traction-
separation relationship across fracture surfaces, which approximates the nonlinear fracture …

Disorder and long-range interactions are two of the key components that make material
failure an interesting playfield for the application of statistical mechanics. The cornerstone in …

Making materials lightweight while attaining a desirable combination of mechanical, thermal,
and other physical properties is the “holy grail” of material science. Lattice materials …

The paper describes two-dimensional meso-scale numerical results of fracture in notched
concrete beams under quasi-static three-point bending. Concrete was modelled as a …

The paper focuses on the DEM modelling of the behaviour of plain concrete during uniaxial
compression and uniaxial tension using the discrete element method. The model takes into …

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 …

The paper describes experimental and numerical results of concrete fracture under quasi-
static uniaxial compression. Experimental uniaxial compression tests were performed on …

The size effect on the fracture process zone in notched and unnotched three point bending
tests of concrete beams is analysed by a meso-scale approach. Concrete is modelled at the …

A meso-scale analysis is performed to determine the fracture process zone of concrete
subjected to uniaxial tension. The meso-structure of concrete is idealised as stiff aggregates …
