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:

Identification of nonlinear fracture properties from size effect tests and structural analysis based on geometry-dependent r-curves
TL;DR: In this paper, the size effect method, previously developed for concrete and mortar, is demonstrated for rock and the measured maximum load values are used to obtain fracture energy, fracture toughness and effective size of the fracture process zone.

An elasto-plastic damage model for plain concrete subjected to high temperatures
TL;DR: In this paper, a computational model allowing for the thermo-mechanical analysis of concrete structures at high temperatures by means of the finite element method is presented, where degradation of a part of the mechanical properties due to temperature is given through a diffused thermal damage model.

Numerical analysis of size effects on open-hole tensile composite laminates
TL;DR: In this paper, the authors presented a computational study of the tensile strength prediction of open-hole laminates using a cohesive zone model and found that neglecting delamination in the numerical models will lead to mesh-dependency and over-estimation on the predicted strength.
Journal ArticleDOI
Cohesive-zone models, higher-order continuum theories and reliability methods for computational failure analysis
TL;DR: In this article, a concise overview is given of various numerical methods that can be used to analyse localization and failure in engineering materials. The importance of the cohesive zone approach is emphasized and various ways to incorporate the cohesive-zone methodology in discretization methods are discussed.

G.Appa Rao,B. K. Raghu Prasad +1 more
TL;DR: In this article, an experimental investigation on the fracture properties of high-strength concrete (HSC) is reported, where three-point bend beam specimens of size 100 x 100 x 500 mm were used as per RILEM-FMC 50 recommendations.
