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 …

Abstract Pultruded Fiber-Reinforced Polymers (FRP) are innovative structural elements that
are experiencing a steady increase in use for different structural applications. Due to their …

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 …

This paper explores buildability quantification of randomly meshed 3D printed concrete
objects by considering structural failure by elastic buckling. The newly proposed model …

Irregular lattices are used to model three‐dimensional (3D) structural components consisting
of a bulk material, curvilinear reinforcement, and their interface. Domain discretization is …

In this research, a novel three-dimensional Bonded Block Model (BBM) for the Discrete
Element Method is proposed for the simulation of transversely isotropic rocks. The model …

The discrete modeling of individual fibers in cement-based materials provides several
advantages, including the ability to simulate the effects of fiber dispersion on pre-and post …

In this work, the lattice model is applied to study the printing process and quantify the
buildability (ie, the maximum height that can be printed) for 3D concrete printing (3DCP) …

Prediction of failure mechanisms in concrete is a fairly complex task due to heterogeneous
concrete microstructure, localization process triggered by cracks, multiple crack interactions …

Discrete fine-scale models, in the form of either particle or lattice models, have been
formulated successfully to simulate the behavior of quasi-brittle materials whose mechanical …
