最近关于粒状材料快速变形的理论试图利用变形粒状物质的颗粒与不平衡气体分子之间的相似性。然后，可以使用动力学理论的方法来确定例如密度、速度和能量的平衡定律的形式，并计算动量和能量的平均通量的具体形式，以及在这些耗散系统中，碰撞中能量损失的平均速率。
Recent theories for rapid deformations of granular materials have attempted to exploit the similarities between the grains of deforming granular mass and the molecules of a disequilibrated gas. Methods from the kinetic theory may then be used to determine, for example, the form of the balance laws for the means of density, velocity, and energy and to calculate specific forms for the mean fluxes of momentum and energy and, in these dissipative systems, the mean rate at which energy is lost in collisions.
