Abstract
Understanding of deformation mechanisms of porous materials under shock compression is important for predicting the material response under shock loading. The meso-scale set-up of the present work considers a set of solid particles separated by air that represents a volume of a porous material. Condensed material in this set-up is simulated with a material model taking heat conduction into account formulated from the principles of extended irreversible thermodynamics. The meso-scale simulation of the shock loading of a representative porous material volume attempts to analyse the material compression by considering inter-constituent heat transfer. The analysis confirms that heat exchange and conductivity might be a significant contributor to the Hugoniot abnormality of highly porous materials.
