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:

Multi-scale cohesive laws in hierarchical materials
Haimin Yao,Huajian Gao +1 more
TL;DR: In this article, the effects of structural hierarchy on flaw insensibility of materials from the viewpoint of multi-scale cohesive laws are investigated, and two idealized, self-similar models of hierarchical materials, one mimicking gecko attachment system and the other mimicking the mineral-protein composite structure of bone, are considered.

Predicting the residual strength for environmentally degraded adhesive lap joints
TL;DR: In this paper, a cohesive zone model was used to predict the residual strength of degraded adhesively bonded lap joints, and a mixed mode interfacial rupture element was proposed with a traction-separation law.
Journal ArticleDOI
A triaxiality and Lode parameter dependent ductile fracture criterion
Ravi Kiran,Kapil Khandelwal +1 more
TL;DR: In this article, a fracture locus is obtained by performing micromechanical analyses on the computational cells by deforming computational cells along paths of predefined stress states described by two dimensionless stress-state parameters: stress triaxiality (T σ ) and Lode parameter (L ).

Behaviour of steel beam to concrete-filled SHS column frames: Finite element model and verifications
TL;DR: In this paper, the authors presented the behavior of the composite frame with concrete-filled square hollow section (SHS) columns to steel beam, under a constant axial load on columns and a lateral cyclic load on the frame.

Fracture energy-based optimisation of steel fibre reinforced concretes
TL;DR: In this article, the combined effect of water/cement ratio, steel fibre tensile strength and volume fraction of fiber on mechanical behavior of steel fiber reinforced concrete (SFRC) was investigated.
