Abstract

In this paper we propose a mortar algorithm for the study of contact mechanics in three dimensional elasticity problems. The projection surface used for integrating the equations is selected through a local cartesiana base defined in each contact element. In this way, some difficulties [...]

Abstract

The extended system is known as a reliable algorithm for the direct computation of instability points on the equilibrium path of mechanical structures. This article describes the application of the extended system as critical point computation method to mechanical contact problems. [...]

Abstract

Underground construction involves all sort of challenges in analysis, design, project and execution phases. The dimension of tunnels and their structural [...]

Abstract

A modular discrete element framework is presented for large-scale simulations of industrial grain-handling systems. Our framework enables us to simulate [...]

Abstract

Comparative studies of different discrete element models of a rock-type material are presented. The discrete element formulation employs spherical particles with [...]
