In the Part I of the paper, structure of granular aggregates obtained after compaction of poly- and mono-dispersed spherical particles was characterized in terms of the coordination number, particles contacting forces and volume fraction distribution

The paper presents two part investigation into the behaviour of poly- and monodispersed granular material applying the discrete element method (DEM). Granular aggregates involve the compaction of spherical particles within the wall-bounded domain und

In the short term, the Euorocode‐based techniques will be implemented as the main design specifications for structural engineers from the member‐states of the European Union instead of the national standards. Therefore, it is of primary importanc

The paper proposes numerical and analytical models of the time-dependent analysis of a multilayered composite. These models enable us to predict the time-dependent behaviour of composite structures made of materials having age-variable properties. Th

It is very important to take into account time-dependent non-elastic deformations and variation of concrete mechanical characteristics in analysis of concrete structures. In codes of many countries, such as ENV 1992-1-1 (Eurocode) [1], ACI 209–92 (

The frictional dissipation and energy stored in two spherical grains are investigated analytically for the sliding or combined slip-sliding regimes for the experimentally-typical cases of testing. The analytical formulae are proposed for the explicit

Flow analysis of pea grains in a three-dimensional, flat-bottomed bin made of Plexiglas is quantitatively investigated regarding the discharge velocities generated experimentally and those predicted using micro- and macro-mechanical approaches. The d

The analytical modelling of coupled slip and sliding contact response of two elastic spheres is presented for the kinematically imposed sphere centre relative motion trajectories. One sphere is assumed as a fixed, the other translating along a specif
