This paper focuses on the importance of taking into account scattering of material parameters (zinc in this example) to perform sheet metal forming simulations. The approach described in this paper is efficiently pragmatic to consider as inputs the materia ...
In this study, the hot deformation behavior of an Al-1% Mg alloy with very coarse initial grain size was investigated in terms of flow stress evolution and grain refinement mechanism. The large grain size was employed to study the traditional continuous dy ...
We examine strain modification of adsorbate adsorbate inter- action in the (C*+S*)/fcc-Ru(211) system for relevance to biomass to hydrocarbon catalysis and the broader case of interaction changes under strain. Applied biaxial strains from -3% to +3% shift ...
Spliced longitudinal reinforcement may result in a reduction of both strength and displacement capacity of reinforced concrete (RC) members. This applies in particular when lap splices are located in regions where inelastic deformations concentrate, such a ...
Accurate modeling of the time-dependent behavior of geomaterials is of great importance in a number of engineering structures interacting with soft, highly compressible clay layers or with organic clays and peats. In this work, a uniaxial constitutive mode ...
In this article, the hot deformation mechanism of a laser-welded near a TA15 Ti-alloy joint was studied by hot tensile tests conducted at temperatures ranging from 800 degrees C to 900 degrees C with strain rates ranging from 1.0 x 10(-1) s(-1) to 1.0 x 10 ...
The macroscopic friction of particulate materials often weakens as the flow rate is increased, leading to potentially disastrous intermittent phenomena including earthquakes and landslides. We theoretically and numerically study this phenomenon in simple g ...
The aim of the present thesis is to model numerically the dynamic failure behavior of concrete at the mesoscale. Concrete is the world's most widely used construction material and the structures made of it are subjected to dynamic loads during their long s ...
We investigate theoretically and numerically the impact of the transition from laminar to turbulent flow on the propagation of a height contained hydraulic fracture (i.e. PKN geometry). We account for the inertial terms in the balance of momentum and expre ...
We analyze the dynamic failure of concrete using two and three-dimensional finite-element models. In particular, the current results extend, using a unique parallel computing approach, previously published two-dimensional results. Concrete is treated at th ...
