Size limitations of testing equipment often imply that samples of coarse granular materials must be scalped or scaled, to reduce the size of the constitutive particles, before they can be tested either by triaxial or direct shear in the laboratory. The objective of the investigation is to Read more... about Trends in the Evolution of Particle Morphology with Size in Colluvial Deposits Overlying Channel Iron Deposits

By means of two dimensional contact dynamics simulations, we analyzed the effect of the particle size distribution (PSD) on the shear strength of granular materials composed of un-breakable discs. We modelled PSDs with a normalized beta function, which allows for building S-shaped gradation Read more... about Does modifying the particle size distribution of a granular material alter its shear strength?

The Carena project is located at Puerto Belgrano Naval Base in Bahía Blanca, Buenos Aires Province in Argentina. The project consists of the temporary watertight closure of dry dock Nº. 2 for maintenance and repair of the dock’s infrastructure. The closure was effected by means of a cellular Read more... about Mechanical characterization of a hydraulic fill sand and FEM simulation of cellular cofferdams at Carena project
