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 …

Concrete can be considered as a heterogeneous material at mesoscale comprising of
several constituents such as aggregates, mortar and Interfacial Transition Zone (ITZ) …

Fracture and Size Effect in Concrete and Other Quasibrittle Materials is the first in-depth text
on the application of fracture mechanics to the analysis of failure in concrete structures. The …

A numerical model for rock is proposed in which the rock is represented by a dense packing
of non-uniform-sized circular or spherical particles that are bonded together at their contact …

The interface friction force between steel and Ultra-high performance concrete (UHPC) can
significantly enhance the shear loading capacity and fatigue performance of steel-UHPC …

Modeling of the evolution of distributed damage such as microcracking, void formation, and
softening frictional slip necessitates strain-softening constitutive models. The nonlocal …

Concrete is considered as a 3-phase composite material; mortar matrix, aggregates, and
interfacial transmission zone (ITZ). In order to investigate the contribution of each phase to …

This paper deals with the formulation, calibration, and validation of the Lattice Discrete
Particle Model (LDPM) suitable for the simulation of the failure behavior of concrete. LDPM …

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

In this paper three-dimensional geometrical models for concrete are generated taking the
random structure of aggregates at the mesoscopic level into consideration. The generation …
