Using nano-technology materials in the asphalt pavement industry is new compared with Portland cement concrete. The main objective of this study is to investigate the effects of nano-silica modification on some properties of a penetration grade asphalt cement and a typical asphalt concrete. 60/70 penetration grade bitumen was modified with different percentages of nano-silica (i.e. 1, 3 and 5%,...

ÐQuasi-static and dynamic compression and three-point bending tests have been carried out on Haliotis rufescens (abalone) shells. The mechanical response of the abalone shell is correlated with its microstructure and damage mechanisms. The mechanical response is found to vary signi®cantly from specimen to specimen and requires the application of Weibull statistics in order to be quantitatively ...

Two state-of-the-art analytical compression after impact (CAI) modelling approaches are presented and evaluated for the problem of thin-film buckle-driven propagation a delamination in composite laminates. Characteristic phenomena investigated by evaluating behaviour energy release rate an anisotropic sublaminate above 2D embedded delamination. These characteristics include extension-bend, shea...
