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 …

Rapid progress in additive manufacturing methods has created a new class of ultralight
mechanical metamaterials with extreme functional properties. Their application is ultimately …

Rigorous characterization of fracture evolution in quasi-brittle materials–such as concrete–
requires computationally intensive and, mostly, complex approaches. However, the …

Many modern engineering structures are composed of brittle heterogenous, or quasibrittle,
materials. These include concrete, composites, tough ceramics, rocks, cold asphalt mixtures …

Abstract Failure processes in Laminated Fiber-Reinforced Composites (LFRCs) entail the
development and progression of different physical mechanisms and, in particular, the …

Dynamic compact tension tests in concrete are investigated using an intermediately-
homogenized peridynamic (IH-PD) model, and the results are compared with a fully …

The recently conceived gap test and its simulation revealed that the fracture energy Gf (or
Kc, Jcr) of concrete, plastic-hardening metals, composites, and probably most materials can …

In the last decade the self-healing of cracks in cementitious materials has been gaining an
increasing interest by both the concrete industry and the scientific community. Framed into …

In the standard fracture test specimens, the crack-parallel normal stress is negligible.
However, its effect can be strong, as revealed by a new type of experiment, briefly named …

This paper focuses on the simulation of irregular stone masonry by the lattice discrete
particle model (LDPM), which simulates the fracture and failure behavior of quasi-brittle …
