Temperature and strain rate effects of jammed granular systems: experiments and modelling

Abstract Jammed granular systems, also known as vacuum packed particles (VPP), have begun to compete with the well commercialized group of smart structures already widely applied in various fields industry, mainly civil and mechanical engineering. However, engineering applications VPP are far ahead mathematical description complex mechanisms observed these unconventional structures. As their wider commercialization is hindered by this gap, paper authors consider experimental investigations focusing on responses that take place under temperature strain rate conditions. To capture nonlinear behavior jammed a constitutive model constituting an extension Johnson–Cook was developed presented. green The extended modified for proposed could be implemented future into commercial Finite Element Analysis code, making it possible carry out fast reliable numerical simulations.
