Physical Experiments with Medium Granular Models under Lateral Passive Pressure

A number of objections may be raised against the contemporary earth pressure theory. On the basis of theoretical considerations, physical and numerical experiments an advanced General Lateral Pressure Theory (GLPT) is being developed at actual stage. The long-term physical experimental research of lateral pressure has been proceeding since 1996. Original stand and pressure sensors were develope...

Compaction dynamics of a granular medium under verti - cal tapping

– We report new experimental results on granular compaction under consecutive vertical taps. The evolution of the mean volume fraction and of the mean potential energy of a granular packing presents a slow densification until a final steady-state, and is reminiscent to usual relaxation in glasses via a stretched exponential law. The intensity of the taps seems to rule the characteristic time of...

Investigation of Swelling Behavior and Mechanical Properties of a pH-Sensitive Superporous Hydrogel Composite

   The objective of the present study is to develop and investigate the swelling behavior of pH-sensitive Superporous Hydrogel (SPH) and SPH composite (SPHC). A novel superporous hydrogel containing poly (methacrylic acid-co-acrylamide) was synthesized from methacrylic acid and acrylamide through the aqueous solution polymerization, using N,N-methylenebisacrylamide as a crosslinker and ammonium...

Synthesis and Swelling Behavior of Gelatin-Based Hydrogel Nanocomposites

In this work, a series of hydrogel nanocomposites were prepared by grafting acrylic acid and acrylamide on gelatin in the presence of Na-montmorillonite (Na-MMT) nanoparticles. The characterizations of hydrogel nanocomposites were examined by swelling experiments, Fourier transform infrared (FT-IR) spectroscopy, X-Ray diffraction (XRD) patterns and thermogravimetric analysis (TGA). Scanning ele...
