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:

Simulation of delamination in fiber composites with a discrete cohesive failure model
TL;DR: In this paper, a discrete cohesive crack model is derived by postulating the existence of a maximum load surface which limits the adhesive forces in the process zone of the crack, and the model is implemented in the explicit finite element code LS-DYNA and simulation results are found to be in agreement with experimental results.

Zdenek P. Bazant,Jia Liang Le +1 more
TL;DR: In this paper, a rigorous theory with detailed derivations yet no superfluous mathematical sophistication; extensive experimental verifications; and realistic approximations for design are vanquished in this book, which includes a wide range of subjects, including probabilistic fracture kinetics at nanoscale, multiscale transition, statistics of structural strength and lifetime, size effect, reliability indices, safety factors, and ramification to gate dielectrics breakdown.

Journal ArticleDOI
Application of constitutive models in European codes to RC–FRC
TL;DR: In this article, the structural behavior of RC-FRC elements with steel fibers and with plastic fibers is compared and a numerical simulation is performed to evaluate their differences in terms of the structural behaviour predicted and measured in an experimental program.

Numerical fracture analysis on the specimen size dependency of asphalt concrete using a cohesive softening model
TL;DR: In this paper, the authors applied the clustered discrete element method (DEM) approach into the investigation of size effect on fracturing of asphalt concrete based on a disk-shaped compact tension (DC(T)) test.
