Analysis of crack formation and crack growth in concrete by means of fracture mechanics and finite elements
TLDR
In this article, fracture mechanics is introduced into finite element analysis by means of a model where stresses are assumed to act across a crack as long as it is narrowly opened, which may be regarded as a way of expressing the energy adsorption in the energy balance approach.About:

Formulation, identification and use of interface models in the numerical analysis of composite delamination
TL;DR: In this article, a numerical integration method for the interface constitutive laws is proposed, and the related consistent tangent modulus is derived, and an algorithm for the structural analysis in the presence of softening interfaces is presented.

Continuum–discontinuum analysis of failure mechanisms around unsupported circular excavations in anisotropic clay shales
TL;DR: In this article, an alternative numerical approach based on nonlinear fracture mechanics principles and the discrete element method is adopted to gain new insight into the failure process of this class of geomaterials.

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.

Scaling of quasibrittle fracture: asymptotic analysis
TL;DR: In this paper, an asymptotic theory of scaling governing the size effect of quasibrittle cracks is presented, while its extension to fractal cracks is left to a companion paper.
Journal ArticleDOI
Mixed Mode Fracture of Concrete under Proportional and Nonproportional Loading
TL;DR: In this paper, a testing procedure for mixed-mode crack propagation in concrete is presented: four-point bend of notched beams under the action of two independent force actuators.
