This paper investigates the role of force chains in granular materials under both quasi-static biaxial loading and dynamic impact conditions. study is mainly interested investigating on global mechanical responses samples as well microstructure materials. For this purpose, discrete element methods are adopted to perform different tests. Granular modelled aggregations poly-disperse spherical particles. Results first show that responsible for strength sample: 2D test, establishment buckling...
Abstract This paper presents a micromechanical study of unsaturated granular media in the pendular regime, based on numerical experiments using discrete element method, compared with microstructural elastoplastic model. Water effects are taken into account by adding capillary menisci at contacts and their consequences terms force water volume studied. Simulations triaxial compression tests used to investigate both macro micro‐effects partial saturation. The results provided two methods...
Rationale: Data on respiratory muscle performance in children with neuromuscular disorders are limited.Objectives: The aim of this study was to assess strength by volitional and nonvolitional tests compare these forced vital capacity.Methods: Inspiratory assessed measuring transdiaphragmatic esophageal pressures generated during maneuvers, whereas expiratory the gastric pressure a cough maneuver. Lung volumes were capacity.Measurements Main Results: Forty-one patients Duchenne muscular...
Abstract This paper presents a synthesis of the works performed by various teams from France, Italy and Canada around question second‐order work criterion. Because non‐associative character geomaterials plastic strains, it is now recognized that whole bifurcation domain exists in stress space with possible modes failure. In first part these failure are observed lab experimental tests discrete element modelling. Then theoretical study allows to establish link kinetic energy, giving basis...
Abstract The concept of failure is one the most debated in soil mechanics, for two reasons essentially. First, this a crucial issue engineering structures and geotechnical project design. Second, still challenging academic mobilizing significant scientific interest development unique framework to describe different modes. In respect, paper revisits localized mode, replacing well‐known Rice criterion within wider context bifurcation. Considering micro‐mechanical model, main theoretical...
Abstract In this paper, the ability of a material rate‐independent system to evolve toward another mechanical state from an equilibrium configuration, with no change in control parameters, is investigated. From point view, means that can spontaneously develop kinetic energy external disturbance state, which corresponds particular case bifurcation. The existence both conjugate incremental strain and stress such second‐order work vanishes established as necessary sufficient condition for...
