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 …

Numerical modelling at the mesoscale is a time-and cost-efficient tool to optimize concrete
mix design and to analyse the phenomenological causes of mechanical failure, eg when …

In this work, a localizing gradient damage model (LGDM) based on the generalized
micromorphic theory is adopted to investigate the quasi-brittle fracture behaviour of concrete …

Hydraulic fracturing of saturated brittle rock is a common discontinuous multi-physics
phenomenon. The evolution and flow behavior of hydraulic fractures are the key to multi …

This paper proposes formulae for refined models that account for wall effects when
modelling the geometric mesostructure of concrete. The wall effect should be taken into …

In this research, a novel integrated wavelet-learning approach with high-accuracy and
efficient prediction capability is developed to predict the effective elastic properties of …

During their life span, concrete structures interact with many kinds of external mechanical
loads. Most of these loads are considered in advance and result in reversible deformations …

Damage in concrete structures initiates as the growth of diffuse microcracks that is followed
by damage localisation and eventually leads to structural failure. Weak changes such as …

A new model for the multi-scale simulation of solute transport in concrete is presented. The
model employs plurigaussian simulations to generate stochastic representations of concrete …

Ultrasonic measurements are used in civil engineering for structural health monitoring of
concrete infrastructures. The late portion of the ultrasonic wavefield, the coda, is sensitive to …
