本文对颗粒材料的动力学方程及其解进行了理论研究，其机械行为由亚塑性理论的本构方程描述。本文讨论了动态问题的适定性、颗粒材料的循环剪切、动态解中横向和纵向位移分量之间的耦合、这种耦合导致的双频效应以及动态循环剪切引起的饱和颗粒固体的液化。
The paper presents a theoretical study of the dynamic equations and their solutions for a granular material whose mechanical behaviour is described by a constitutive equation of the hypoplasticity theory. Discussed in the paper are well-posedness of the dynamic problem, cyclic shearing of a granular material, the coupling between the transverse and the longitudinal displacement components in the dynamic solutions, the double-frequency effect as a consequence of this coupling, and liquefaction of a saturated granular solid caused by the dynamic cyclic shearing.
