Discrete models of solids have been motivated, in large part, by the discontinuous and
heterogeneous nature of material structure and its breakdown under loading. The …

Concrete can be considered as a heterogeneous material at mesoscale comprising of
several constituents such as aggregates, mortar and Interfacial Transition Zone (ITZ) …

This paper focuses on the numerical modelling of autogenous and stimulated healing of
cracks in fibre-reinforced cementitious composites, with the aim of showing the potential that …

In the last decade the self-healing of cracks in cementitious materials has been gaining an
increasing interest by both the concrete industry and the scientific community. Framed into …

This study presents the formulation and validation of a three-dimensional Flow Lattice Model
(FLM) with application to the Hygro-Thermo-Chemical (HTC) model for analysis of moisture …

A better understanding of moisture migration in concrete at high temperature can play an
important role to improve the fire-resistance and radiation-shielding capability of concrete …

The tensile response of steel fibre reinforced concrete (SFRC) placed in a given structural
element is strongly dependent on the final fibre distribution and orientation with respect to …

For high stress levels, the dependence of the creep strain rate of concrete on the acting
stress is nonlinear. Furthermore, very high stress levels may lead to a critical growth of …

Part II of the study of a wet mix shotcrete focuses on creep and shrinkage as well as on the
thermal and hygral behavior. It deals with the time-dependent mechanical behavior due …

From experimental perspective, it is well-known that relationship between concrete creep
and loading level is nonlinear at middle and high loading levels. This nonlinear …
