Quasi-Static Deformation of a Granular System with a Regular Arrangement of Particles

In order to study the growth of heterogeneity in granular systems, we investigate the quasi-static deformation of monodisperse particle systems with regular initial arrangements. We construct a linearized model by limiting our consideration to infinitesimal deformations. Assuming Coulomb friction, we introduce new variables to express the slippage distances of particles in contact. The results ...

A Quasi-Static Method for Large Deformation Problems in Geomechanics

The Finite Element Method (FEM) has become the standard tool for the analysis of a wide range of mechanical problems. However, the classical FEM is not well suited for the treatment of large deformation problems since excessive mesh distortions require remeshing. The Material Point Method (MPM) represents an approach in which material points moving through a fixed finite element grid are used t...

Deformation-driven diffusion and plastic flow in amorphous granular pillars.

We report a combined experimental and simulation study of deformation-induced diffusion in compacted quasi-two-dimensional amorphous granular pillars, in which thermal fluctuations play a negligible role. The pillars, consisting of bidisperse cylindrical acetal plastic particles standing upright on a substrate, are deformed uniaxially and quasistatically by a rigid bar moving at a constant spee...

Constitutive model for quasi-static deformation of metallic sandwich cores

All-metal sandwich construction holds promise for significant improvements in stiffness, strength and blast resistance for built-up plate structures. Analysis of the performance of sandwich plates under various loads, static and dynamic, requires modelling of face sheets and core with some fidelity. While it is possible to model full geometric details of the core for a few selected problems, th...

Quasi-Static Deformation of a Uniform Thermoelastic Half –Space Due to Seismic Sources and Heat Source

This paper investigates the quasi-static plane deformation of an isotropic thermoelastic half-space due to buried seismic sources and heat source. Governing equations of thermo-elasticity are solved to obtain solutions for seismic sources in a thermoelastic half-space. The general solutions are acquired with the aid of Laplace and Fourier transforms and with the use of boundary conditions. The ...
