Reinforcement problems in elasto-plasticity

open access: yesRocky Mountain Journal of Mathematics, 1980
the material has become plastic (see [7] [13]). This problem was studied by various authors in the case of a homogeneous material, i.e., A(x) = const., g(x) = const, (see [2] [3] [5] [6] [10] [13] [18] and the references given there). In this paper we are interested in the case of variable A, g and, more specifically, in the case where Q is a disjoint ...

Intrusive Magmatism, Plate Stresses, and the Cause of Orthogonal Versus Oblique Spreading Mid‐Ocean Ridges

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The origin of orthogonally spreading ridge segments separated by oceanic transform faults, versus obliquely spreading ridge segments without transform faults (TFs), is a long‐standing enigma of plate tectonics. We address this problem using three‐dimensional (3D) geodynamic models that simulate axial magmatic intrusions along two ridge ...

Structure and Calibration of Constitutive Equations for Granular Soils

open access: yesStudia Geotechnica et Mechanica, 2015
The form of incremental constitutive equations for granular soils is discussed for the triaxial configuration. The classical elasto-plastic approach and the semi-empirical model are discussed on the basis of constitutive relations determined directly ...

From elasto-plasticity to visco-elasto-plasticity for saturated granular materials

open access: yes, 2015
A recent extension of the discrete element method is reported for the simulation of dense mixtures of non-colloidal particles and viscous fluids in the non-inertial regime. The numerical model includes sphere-sphere contacts using a soft contact ap- proach [2], short range hydrodynamic interactions defined by frame-invariant expressions of forces and ...
