英文摘要Dry granular materials consist of a collection of macroscopic discrete particles interacting solely via contact forces. By changing the external conditions, the granular packing displays rich phenomena ranging from fluid-like properties to jamming glassy behavior and to aging observed when these grains are trapped in a frozen state. Once the grains contact liquid, the force between the liquid and grains has an influence on the mechanical properties of the wet granular materials, and some mechanical behaviors are quite different from those of the dry granular materials. However, the underlying mechanism of the complex dynamics of granular assemblies is still not completely understood. In this paper, mechanical spectroscopy (the shear modular G and the related energy dissipation tan phi) of NaCl wet granular system is investigated with different liquid content (weight fraction) under the constant temperature 25 degrees C and air humidity by a modified low-frequency inverted torsion pendulum. The NaCl wet granular system also displays jamming behavior when subjected to an external vibration with increasing intensity, which is quiet similar to dry granular matter. With the increase of water content, all the spectra of tan phi and modular G show a peak at the water content about 11% (critical water content). At the same time, the applied shear force has little influence on the positions of these peaks. All of these behaviors illustrate that the main interaction forces among granular matters in the system are changed at the moment.
