In this work, a critical comparison between three different numerical approaches for the
computational modelling of quasi-brittle structural failure is presented. Among the many …

Rigorous characterization of fracture evolution in quasi-brittle materials–such as concrete–
requires computationally intensive and, mostly, complex approaches. However, the …

This paper checks the consistency of some published exponential and bilinear mixed-mode
cohesive zone models. The effect of coupling on traction-separation behavior and energy …

The recent generation of polyolefin-based macro-synthetic fibres have shown to meet the
requirements of the standards for structural use. Therefore, polyolefin fibres have become an …

In this paper we focus on the prediction of mode-I debonding for a double cantilever beam
(DCB). Among the various modeling approaches available, the Cohesive Crack Model …

Research has shown that polyolefin fibres can meet the requirements of the standards that
consider their post-cracking contribution in the structural design of fibre reinforced concrete …

The importance of crack propagation in the structural behaviour of concrete and masonry
structures has led to the development of a wide range of finite element methods for crack …

The exceptional mechanical properties that glass fibre reinforced cement (GRC) boasts are
the result of the interaction of the fibres and the brittle matrix. While the cement mortar …

The interfacial transition zone (ITZ) between cement paste and aggregates in concrete plays
an important role in the macro-mechanical properties of concrete. It generally exhibits as a …

In recent years, polyolefin fibres have proved a remarkable performance as reinforcement of
concrete, which has inspired a number of studies involving, among others, the simulation of …
