This paper reviews the state of the art of the impact resistance of ordinary fiber-reinforced
concretes (FRCs) containing various fibers. First, various types of impact test methods that …

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 …

Yade is an extensible open-source framework for discrete numerical models, focused on the
Discrete Element Method. The computation parts are written in c++ using a flexible object …

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

This study aims to explore dynamic behaviours of fracturing and damage evolution of rock
materials at the grain scale. A grain-based discrete element method (GB-DEM) is proposed …

In this paper, crack propagation and coalescence behaviors in rock specimens containing
pre-existing open flaws under uniaxial compression are investigated using the novel …

Many large engineering projects, eg, the Sichuan–Tibet Railway, inevitably cross the
earthquake active areas and the geology complicated zones, facing the challenges of …

Our living standards are substantially influenced by the advent and development of new
materials. The need for stronger building materials has led to useful innovations such as the …

Understanding the strain rate effects on cement-based materials are important for accurately
modeling concrete structure damage to high-velocity impact and blast loads. This paper …

A micro-mechanical based numerical manifold method (NMM) is proposed in this study to
investigate the micro-mechanisms underlying rock macroscopic response and fracture …
