Sensitivity of the stress response function to packing preparation

Abstract: A granular assembly composed of a collection of identical grains may pack under different microscopic configurations with microscopic features that are sensitive to the preparation history. A given configuration may also change in response to external actions such as compression, shearing etc. We show using a mechanical response function method developed experimentally and numerically, that the macroscopic stress profiles are strongly dependent on these preparation procedures. These results were obtained for b… Show more

“…Em 2005, Atman et al [1] analisaram os perfis de respostaàs tensões para sistemas granulares sujeitos a preparações distintas. Nesse artigo, discutiu-se sobre medições experimentais em arranjos bidimensionais construídos com grãos fotoelásticos, experimentos em pilhas tridimensionais e, finalmente, apresentaram dados obtidos por meio de simulações numéricas de empilhamentos granulares.…”

“…The response of granular media to local perturbations have been studied widely both in experiments [4,5,6,7,8] and in computer simulations [8,9,10,11]. The majority of these studies apply small force overloads to study the stress response inside the bulk of material.…”
