Numerous industries involve impact crushing of raw material in their processes. Crushing is performed by interaction between raw material witch size is reduced during this process and equipment or parts that crush. Some of the biggest and most important clients of crushing and milling equipment are industries like cement plants, mines, open pits, coal fired thermal plants, recycling and shreddi...

Particle crushing dominates the deformation behaviour of granular materials under significantly high compressive and shear stress. A proposed constitutive model has been verified to predict crushing behaviour of granular materials with different crushability and adopted one kind of reference crushing stress. It is noted that no positive dilatancy of granular material in triaxial test occurs onc...

Limitation of forces can be a simple measure to safeguard crushing points at doors, machines, and vehicles. In this connection different standards define a threshold force value of 150 N. This widely accepted value refers to static forces only. The dynamic forces that arise from impact on a person are frequently ignored, although they are generally higher than the static forces. The article des...

Application of impact energy absorption systems in different industries is of special significance. Thin-walled tubes, due to their lightness, high energy absorption capacity, long crushing length and the high ratio of energy absorption to weight, have found ever-increasing application as one of the most effective energy absorption systems. In this research, through  carrying out experimental t...

The energy absorbing capability is one of the most important aspects of crushing behavior of a structure subjected to axial impact. In this paper, a simple practical method is introduced to enhance the crushing behavior of this kind of structure. The axial impact of metallic energy absorbing thin-walled tubes with special shaped cross-section is simulated using LS-DYNA software. The effect of c...

In this study, the crashworthiness performance of a multi-cell column designed from B1500HS boron steel with three different hardness values and six regional hot-formed designs were compared in terms passenger safety. Energy absorption peak crushing force columns examined by impact simulations under oblique loading. “T25 heat-treated column” gave highest energy value, while "O25 column" lowest ...
