The distribution of particles (e.g. micro and nanoinclusions, carbon nanotubes, carbon nanofibers) within a composite material plays a vital role in dictating many important constitutive properties. In this study, a general method to quantify the dispersion and agglomeration of nano-particles in composite materials has been developed. The dispersion quantity, D, is measured by the free-path spacing...
A close-form solution is developed for the prediction of the moment–curvature relationship of cross sections of fiber reinforced concrete (FRC) elements failing in bending, and reinforced longitudinally with steel and fiber reinforced polymer (FRP) bars. The FRP bars are installed with the largest possible internal arm, e.g. with the minimum concrete cover that assures the bond conditions for a sound...
