One of the biggest challenges associated with modelling the behaviour of reinforced
concrete is the difficulty of incorporating realistic material models that can represent the …

The K&C material model is widely used to numerically predict the responses of concrete
structures against impact or blast loadings. In the literature, most of the K&C parameters are …

Accidents due to low-velocity impact loading are no longer uncommon these days.
Accordingly, although evaluation criteria for regulating the global behavior of major …

In recent years, a large number of studies have been carried out to investigate behaviours of
concrete filled double skin steel tube (CFDST) members due to its increasing popularity in …

Abstract Karagozian and Case (K&C) concrete model is extensively adopted in the
numerical simulations of ultra-high performance concrete (UHPC) structural members …

Concrete demonstrates complex dynamic mechanical behaviors under the influence of blast
or impact loads, and there are inherent limitations in experimental and theoretical methods …

A description and results from validation studies for the Karagozian & Case (K&C) concrete
(KCC) model are presented in this paper. This material model is primarily intended for …

Concrete filled steel tubes (CFST) have been widely used in constructing high-rise
buildings, arch bridges and factories for the past few decades. In this research, numerical …

Based on Delaunay triangulation, a 3D meso-scale model is successfully developed and
verified. This approach modelling fibre and concrete separately and linking them with slide …

Geopolymer based ultra-high performance concrete (G-UHPC) has been recognized as a
'eco-friendly'form of ultra-high performance concrete owing to its beneficial characteristics …
