Enterprise system implementations often create tension in organizations. On the one hand, these systems can provide significant operational and strategic benefits. On the other hand, implementation of these systems is risky and a source of major disruptions. In particular, employees experience significant changes in their work environment during an implementation. Although the relationship betw...

Under traffic loading, the soil elements in subgrade are subjected to a complex 3D stress path. To investigate cyclic behavior of desert under initial shear conditions, number true triaxial tests were implemented on aeolian sand from Tengger Desert. A large range levels and different paths (various combinations major intermediate principal stresses) designed experiments. The results show that l...

Purpose Although research has suggested that enterprise system (ES) implementations have major impacts on employee job characteristics and outcomes, there been limited examined the of ES interpersonal relationships over time. Building extending recent studies changes in outcomes during an implementation, this nature, extent, determinants important relationship construct—coworker exchange (CWX)—...

Abstract For design and application of particulate reinforced metal matrix composites (PRMMCs), it is essential to predict the material strengths understand how do they relate constituents microstructural features. To this end, a computational approach consists direct methods, homogenization, statistical analyses introduced in our previous studies. Since failure PRMMC materials are often caused...

An interlayer soil was identified in the French conventional rail tracks, corresponding to a mixture of subgrade fine and ballast grains. Experimental results show that permanent strain such fine/coarse can be at stable or unstable state, depending on stress level with respect plastic shakedown limit σ dth (the maximum for strain). As water content changed, matric suction ψ changed subsequently...

When microscopic and macroscopic specimens of metals are subjected to cyclic loading, the creation, interaction, and accumulation of defects lead to damage, cracking, and failure. Here we demonstrate that when aluminum single crystals of submicrometer dimensions are subjected to low-amplitude cyclic deformation at room temperature, the density of preexisting dislocation lines and loops can be d...

This paper analyzes the long-term response of unlined energy storage located at shallow depth to improve the distance between a wind farm and storage. The numerical approach follows the hybrid scheme that combined a mechanical constitutive model to extract stress and strains at the first cycle and polynomial-type strain accumulation functions to track the progressive plastic deformation. In par...

We investigate the cyclic behavior of laminate microstructures in finite-strain crystal plasticity and the resulting stress-strain response, based on a variational, incremental description of the microstructure evolution. The nonconvex free energy density in multiplicative singleand multi-slip plasticity gives rise to the formation of fine-scale deformation structures, experimentally observed a...
