Cohesive, frictional powders: contact models for tension
The contacts between cohesive, frictional particles with sizes in the range 0.1–10μm are the subject of this study. Discrete element model (DEM) simulations rely on realistic contact force models—however, too much details make both implementation and interpretation prohibitively difficult. A rather simple, objective contact model is presented, involving the physical properties of elastic–plasti...
متن کاملShakedown in frictional contact problems for the continuum
Elastic systems with frictional interfaces subjected to periodic loading are often found to ‘shake down’ in the sense that frictional slip ceases after the first few loading cycles. The similarities in behaviour between such systems and monolithic bodies with elastic– plastic constitutive behaviour have prompted various authors to speculate that Melan’s theorem might apply to them—i.e. that the...
متن کاملIsotropic compression of cohesive-frictional particles with rolling resistance
Cohesive-frictional and rough powders are the subject of this study. The behavior under isotropic compression is examined for different material properties involving Coulomb friction, rolling-resistance and contact-adhesion. Under isotropic compression, the density continuously increases according to Bauers exponential law, see Ref. (Bauer 1999). However, at a certain pressure/density, the beha...
متن کاملShakedown of Cohesive-frictional Non-homogeneous Soils under Moving Surface Loads
ABSTRACT: In this paper, shakedown limits of non-homogeneous soils in a half-space under rolling and sliding surface loads are investigated. The inhomogeneity of the soil is described by a power law for the variation of Young’s modulus with the depth. Mohr-Coulomb criterion is employed to characterise the cohesive-frictional behaviour of the soil. Analytical solutions to the elastic stress fiel...
متن کاملStress Field at a Sliding Frictional Contact: Experiments and Calculations
Using a MEMS-based sensing device, we have measured the normal and tangential stress fields at the base of a rough elastomer layer in contact with a smooth glass cylinder in steady sliding. This geometry allows for a direct comparison between the stress profiles measured along the sliding direction and the predictions of an original exact bidimensional model of friction. The latter assumes Amon...
