Simulation and analysis of composite structures
TL;DR: In this paper, it was shown that the geometry of natural rounded aggregates can be simulated by using an appropriate morphological law and with the computer-generated particles, arbitrary composite structures can be generated.
Journal ArticleDOI
Le beton numerique
TL;DR: The authors expose le fait que les different mecanismes qui sont a l'origine du comportement du beton sont si complexes and si dependants les uns des autres qu'il est impossible de les etudier exclusivement par voie experimentale.
Journal ArticleDOI
Influence of age of loading, water-cement ratio and rate of loading on fracture energy of concrete
TL;DR: The applicability of linear elastic fracture mechanics to a composite material such as concrete has always been questioned as discussed by the authors, but little work has been done to determine experimentally major influences on these material parameters.
