Mesoscale models for concrete: homogenisation and damage behaviour
Peter Wriggers,S. O. Moftah +1 more
TLDR
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.About:

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.

Modelling of compressive behaviour of concrete-like materials at high strain rate
Xiaoqing Zhou,Hong Hao +1 more
TL;DR: In this paper, numerical analyses are performed to investigate the compressive behavior of concrete-like material at high strain rates using a homogeneous macro-scale model and a heterogeneous mesoscale model.

Effects of interfacial transition zones on the stress–strain behavior of modeled recycled aggregate concrete
TL;DR: In this paper, the constitutive relationship of the Interfacial Transition Zones (ITZs) in Recycled Aggregate Concrete (RAC) is put forward based on nanoindentation tests and analysis.
Journal ArticleDOI
Monte Carlo simulations of mesoscale fracture modelling of concrete with random aggregates and pores
TL;DR: In this paper, a procedure for generating two-dimensional heterogeneous meso-scale concrete samples is developed, in which the multi-phasic features including the shape, size, volume fraction and spatial distribution of aggregates and pores are randomised.

Multiscale Modeling of Concrete
Jörg F. Unger,Stefan Eckardt +1 more
TL;DR: A multiscale method to couple the homogeneous macroscale with the heterogeneous mesoscale model in a concurrent embedded approach is proposed, which allows an adaptive transition from a full macroscale model to a multiscales model, where only the relevant parts are resolved on a finer scale.

Discrete numerical model for granular assemblies.
Peter Cundall,Otto D. L. Strack +1 more
TL;DR: The distinct element method as mentioned in this paper is a numerical model capable of describing the mechanical behavior of assemblies of discs and spheres and is based on the use of an explicit numerical scheme in which the interaction of the particles is monitored contact by contact and the motion of the objects modelled particle by particle.

The Determination of the Elastic Field of an Ellipsoidal Inclusion, and Related Problems
TL;DR: In this paper, it is shown that to answer several questions of physical or engineering interest, it is necessary to know only the relatively simple elastic field inside the ellipsoid.

Average stress in matrix and average elastic energy of materials with misfitting inclusions
Trevor A. Mori,K Tanaka +1 more
TL;DR: In this paper, a method of calculating the average internal stress in the matrix of a material containing inclusions with transformation strain is presented. But the authors do not consider the effects of the interaction among the inclusions and of the presence of the free boundary.
