The analysis of the exact composition of porous materials, such as concrete or asphalt, and its influence on resulting mechanical material properties plays an extremely crucial role in various ...

The effective mechanical properties of spherical packings composed of soft and stiff spheres are investigated using ultrasonic waves and X-ray. Credit: Matthias Ruf (University of Stuttgart), Kianoosh ...

For centuries, physicists and mathematicians have been trying to work out the most efficient way of packing spheres in order to minimize wasted space. They think they know how to maximise efficiency ...

Porous media such as concrete physically represent a spherical packing of different components -- in this case cement, rock and water. The mechanical properties of such mixtures are still difficult to ...

Porous media such as concrete represent a spherical packing of different components. The mechanical properties of such mixtures are difficult to calculate due to their discretized nature. A team led ...
