\\n \\n The 5th Workshop of Soft Condensed Matter Physics has been held at Minhang Campus of Shanghai Jiao Tong University in China on October 21-23, 2016. About 30 research groups come from China discussed the structure, dynamics, and phase transitions of soft matter, including colloids, granular matter, biological systems, and polymers, etc. This workshop provided a platform for young scholars’ discussion and communication, and enhanced the cooperation among the scholars in soft condensed matter physics field. It will be held at University of Science and Technology of China (USTC) next year.\\n The 5th Workshop of Soft Condensed Matter Physics has been held at Minhang Campus of Shanghai Jiao Tong University in China on October 21-23, 2016.

\\n \\n When a large amount of granular particles pass through an orifice, the flow of particles may be\\nclogged. Many factors can change the probability of clogging, such as the outlet size, the presence of obstacles\\nand external vibrations, but the detailed mechanisms are still unclear. In this paper, we present an experimental\\nstudy of reduction of the probability of clogging in a horizontal plane silo, which consists of a layer of photoelastic\\nparticles transported on an annular flat plate rotating with a constant angular velocity passing through\\na hopper structure.\\n \\n

\\n \\n In this system, the photo-elastic disks rest horizontally on a Plexiglas sheet which is bounded by an outer ring and an inner shearing wheel, which is controlled by a stepper motor. Two SLR cameras are used to obtain the structure and stress information.\\nNow, we investigate the behavior of granular matter near marginal state when continuous shear is applied. Furthermore, we will study plasticity of amorphous solids and the non-local rheology of granular flow.\\n \\n

Granular materials are ubiquitous in nature and are closely related to many industrial processes and natural hazards. There are many novel and intriguing characteristics in granular system. As a classical non-equilibrium system, it has provided a valuable platform for scientists to develop the statistical physics, to understand the phase transition of amorphous materials, and to understand the mechanism of plasticity in material science.\\n
