TLDR
In this paper, the influence of lattice element type and lattice orientation on the fracture pattern was investigated by simulating a shear loading experiment on a concrete plate, and the effect of element resolution on fracture results was also investigated.About:

A bonded-particle model for rock
D.O. Potyondy,Peter Cundall +1 more
TL;DR: In this paper, 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 points and whose mechanical behavior is simulated by the distinct element method using the two-and three-dimensional discontinuum programs PFC2D and PFC3D.

Mesoscale models for concrete: homogenisation and damage behaviour
Peter Wriggers,S. O. Moftah +1 more
TL;DR: In this paper, three-dimensional geometrical models for concrete are generated taking the random structure of aggregates at the mesoscopic level into consideration, where the aggregate particles are generated from a certain aggregate size distribution and then placed into the concrete specimen in such a way that there is no intersection between the particles.

Meso-scale computational modeling of the plastic-damage response of cementitious composites
TL;DR: In this paper, the authors investigated the contribution of each phase to the strength and damage response of concrete, 2D and 3D meso-scale simulations based on a coupled plasticity-damage model are carried out.

Random particle model for fracture of aggregate or fiber composites
TL;DR: In this article, a particle model for brittle aggregate composite materials such as concretes, rocks, or ceramics is presented, which is also applicable to the behavior of unidirectionally reinforced fiber composites in the transverse plane.

Experimental and numerical analysis of micromechanisms of fracture of cement-based composites
Erik Schlangen,J. G. M. Van Mier +1 more
TL;DR: In this paper, the crack face bridges are flexural ligaments between ovelapping crack tips, and the failure of these ligaments occurs in a stable and controlled manner because the two overlapping crack tips shield each other.
