On the Apparent Non-coaxiality of the Tangential Interaction
2016The contact interactions between real particles are extremely complex, and unknown, due to particle shape and surface roughness. In DEM simulations, even for spherical particles, the tangential interaction is complicated. This is due to the fact that, after the old tangential displacement has been rotated to account for the rotation of the contact ...

The characteristics of coaxial and non-coaxial strain paths
Journal of Strain Analysis, 1966In manufacturing processes involving large strains, the properties of the material undergoing deformation depend not only on the current total strain but on the previous strain path as well. Strain paths are divided into two major types, those in which the principal axes of strain remain fixed with respect to the material (coaxial strain paths), and ...

Experiments on hydrodynamic focusing of non coaxial sheath flows
2006 5th IEEE Conference on Sensors, 2006In this paper we present experiments on chip-based non coaxial sheath flows. The uniformity of the sample flow profile along a fluidic channel and the width-limitation of hydrodynamic focusing of the sample flow are demonstrated. Additionally, the influence of varying the flow rate of the horizontal control ports on the sample flow profile is ...

Application of a non-coaxial soil model in shallow foundations
Geomechanics and Geoengineering, 2006The influence of a non-coaxial model for granular soils on shallow foundation analyses is investigated. The non-coaxial plasticity theory proposed by Rudnicki and Rice (J. Mech. Phys. Solids 1975, 23, 371–394) is integrated into a Drucker–Prager model with both perfect plasticity and strain hardening.

Ultrahigh Vacuum Non-Coaxial Linear-Motion Feedthroughs
2009Analysis of linear-motion feedthrough schemes (see Figure 4.2, Chapter 4) shows that sliding speed (V parameter) in kinematic pairs of feedthrough can vary from the maximum value corresponding to the traditional nut-screw couple to zero. The sliding speed variation from maximum value to minimum value leads to a great variation in the design schemes of ...

Estimating Local Head Loss of Non Coaxial Emitters
2009 Reno, Nevada, June 21 - June 24, 2009, 2009The design procedure of a lateral line of trickle irrigation needs to be evaluated accurately, by accounting for head losses distributed in the piping as well as within the emitters. A methodology was developed for determining localized head losses by the formulation of a mathematical model using the concept of an obstruction index.

Elliptical markers and non-coaxial strain increments — discussion
Tectonophysics, 1981Abstract In a recent paper, Siddans (1980) attempts to show that the “unstraining Rf/φ” technique gives an incorrect estimate of non-coaxial strain in a tectonically imbricated ellipse distribution. The model used in the demonstration is shown to be invalid.

Partitioning of non-coaxiality in deforming layered rock masses
Tectonophysics, 1992Abstract Partitioning of non-coaxiality and other flow parameters in deforming layered rock masses with nearly incompressible Newtonian rheology is examined in two dimensions by the finite element method. The results show that layers with viscosity contrast in suitable orientation deform by different and even by a reverse sense of non-coaxiality ...
