Axial crushing of thin-walled structures with origami ...

2012-5-1 · The crushing process of the thin-walled tube can be divided into three stages. First, the crushing force reaches the initial peak to overcome the initial resistance of the tube; second, the force drops and fluctuates around the mean crushing force while the tube deforms; last, the crushing force increases rapidly due to too little space left to compress, marking the end of the crushing process.

Crushing Mechanism for Soil Particles

Typically, soil samples must be crushed into particles for laboratory research. Thus, an efficient mechanism to ensure a uniform particle size is essential. We previously developed a rod mill device that performs well, but video analysis indicated that the shear forces applied by the rod were more effective than the compressive forces applied by the mill.
