This work correlates the resistance of concrete cores with the physical properties of the granular material forming it. A basic physical characterization is conducted, taking into account the origin of the grains involved ...

Esta dissertação de mestrado investiga se a hipótese granular proposta por Gabaix (2011) aplica-se à economia brasileira. Conjectura-se que dado que as economias modernas são compostas por grandes empresas, uma parte ...

The confining pressure P is perhaps the most important parameter controlling the properties of granular matter. Strongly compressed granular media are, in many respects, simple solids in which elastic perturbations travel ...

Context. Dust impact into granular materials leads to crater formation and material ejection. Aims. The impact of dust aggregates, composed of a number Np of grains, into a granular bed consisting of the same grains is ...

Using a granular-mechanics code, we study the impact of a highly porous granular body on a hard wall. The projectile consists of monodisperse adhesive micrometer-sized silica grains. For the impact velocities studied, ...

In road construction, pavements are composed of layers whose strength decreases with depth. The layers on which the wearing courses are laid are called "Base Course". In Ecuador, the characteristics are established in ...
