摘要：

Studies of mechanical behavior of porous elastic-plastic media under shock loading were undertaken within the framework of irreversible thermal dynamics and Debye forms of Helmholtz free energy. The influence of porosity on dilatancy of porous elastic-plastic media is evaluated by the effective deformation method. The state equations derived in the studies match properly irreversible thermodynamics.
