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:

Effects of fiber strength on fracture characteristics of normal and high strength concrete
TL;DR: In this paper, the effects of steel fiber strength on the mechanical properties of reinforced concretes, such as compressive strength, modulus of elasticity, splitting tensile strength, flexural strength, fracture energy and characteristics length have been investigated within the scope of this study.

Effects of aluminum surface treatments on the interfacial fracture toughness of carbon-fiber aluminum laminates
TL;DR: The influence of aluminum surface treatment on the interfacial delamination performance of carbon/epoxy composite and aluminum substrate was studied in this paper, where aluminum substrates were treated chemically with acid, alkaline and both individually.

TL;DR: In this article, numerical investigations were carried out to study the behavior of concrete filled steel tubes having square or rectangular cross-sections, and a parametric study was performed to evaluate the effect of depth-to-thickness ratio (20−200), compressive strength of infilled concrete (2-100 MPa), shear span-todepth ratio (1-8), depth to width ratio (0.6-2), and yield strength of steel tube (380-490 MPa) on the flexural behaviour of square and rectangular CFST members.

A finite element approach coupling a continuous gradient damage model and a cohesive zone model within the framework of quasi-brittle failure
TL;DR: In this paper, a coupled continuous/discontinuous approach involving a gradient damage model and a cohesive zone model is proposed to simulate crack propagation in quasi-brittle materials.
