Meso-scale approach to modelling the fracture process zone of concrete subjected to uniaxial tension

TL;DR: Dual three-dimensional networks of structural and transport elements were combined to model the effect of fracture on mass transport in quasi-brittle geomaterials to be objective with respect to element size and orientation.

TL;DR: In this article, an intermediately homogenized peridynamic (IH-PD) model is used to model the quasi-static fracture behavior in concrete structures. But the model is not suitable for the case of anchor pullout from a concrete plate.

TL;DR: In this article, a meso-scale modeling approach was used to explore the nonlinear bond behavior between ribbed bar and concrete, considering frictional resistance and the mechanical interlocking between rebar and concrete as well as the surface characteristic of crescent ribbed bars.

TL;DR: In this article, the effect of aggregate classes on the fracture behavior of a plain concrete is studied and different simulations are performed from a mesoscopic model based on diffuse meshing technique and Fichant's damage model, in which the smallest aggregates are successively removed from the granular skeleton to the benefit of a homogenized continuous mortar.

TL;DR: In this paper, a self-consistent method for the elastic moduli of bodies containing randomly distributed flat cracks, with or without fluid in their interiors, is proposed and general concepts are outlined for arbitrary cracks and explicit derivations together with numerical results are given.

TL;DR: In this article, the authors presented an efficient method for digital simulation of general homogeneous processes as a series of cosine functions with weighted amplitudes, almost evenly spaced frequencies, and random phase angles.

TL;DR: In this paper, a three-dimensional finite deformation cohesive element and a class of irreversible cohesive laws are proposed to track dynamic growing cracks in a drop-weight dynamic fracture test.

TL;DR: In this article, a consistent numerical solution procedure of the governing partial differential equations is presented, which is shown to be capable of properly simulating localization phenomena, and the introduction of higher-order deformation gradients in the constitutive model is demonstrated to be an adequate remedy to this deficiency of standard damage models.
