  Notes on the effect of grain crushing on the granular soil …

  200211 · Abstract. Two granular materials — alluvial quartzy Zbraslav sand and granular silica gel — were tested with the intention to demonstrate the effect of grain crushing. Stepwise transformation of the compression curve produced by progressive grain crushing was observed. Due to grain crushing, shear strength envelope became …

  A unified fractional breakage model for granular materials inspired …

  202128 · Abstract Particle breakage of granular materials is a phenomenon of great importance in engineering practices. This paper presents a unified particle breakage model for granular materials, which is able to capture the evolution of the particle size distribution (PSD) of each size fraction of particles.

  Crushing strength of artificial single-particle considering the …

  Particle geometry is a result of natural processes, such as the genesis of parent rock, particle transportation and depositional history. For granular materials, the particle morphology has a significant effect on its crushing strength in geotechnical engineering. The particle morphological parameters, sphericity, aspect ratio and convexity can be …

  Understanding Buckling | The Efficient Engineer

  2024310 · This means we can define two distinct regions, one where columns fail by crushing because the stress in the column exceeds the material yield strength (i.e. for stocky columns), and one where they fail due to buckling (i.e. for slender columns).

  Analysis of impact energy absorption and dissipation …

  202211 · Abstract The present study is based on impact energy absorption capacity of different composite plates subjected to dynamic impact loading with 9 mm parabellum bullet. Analytical approach, namely energy method, has been carried out to find the energy absorbed during an impact and simulation of tensile testing is done to get the stress- …

  DEM simulations of stiff and soft materials with crushable …

  2013716 · The mechanical behavior of granular materials is largely affected by particle breakage. Physical and mechanical properties of granular materials, such as grain size distribution, deviatoric and volumetric behavior, compressibility and mobilized friction angle are affected by particle crushing. This paper focuses on the evolution of the above …
