Elasticidad en materiales granulares

Elasticidad en materiales granulares

Abstract

En este trabajo se estudia el comportamiento elástico de compactos de polvos metálicos. Para ello, se han preparado probetas cilíndricas y se han sometido a ensayos de compresión uniaxial con ciclos de carga y descarga. El análisis de las cargas elásticas muestra una elasticidad no lineal, que puede representarse matemáticamente por medio de una ley potencial. Este comportamiento, siempre influido por fenómenos de fricción interna, puede comprenderse mejor utilizando un modelo de dos partículas, comparable al del contacto elástico de Hertz
