Abstract
The stress–strain behaviour of granular materials can be modelled with hypoplastic constitutive relations. A hypoplastic model is briefly introduced for the axially symmetric case, and a procedure for the determination of its parameters is described in detail. It is shown, for several sands and one gravel, that all parameters of the hypoplastic model are closely related to the granulometric properties of grain assemblies. Recalculations of some element tests are presented in order to verify the proposed procedure. Copyright © 1999 John Wiley & Sons, Ltd.
从晶粒组合特性确定亚塑性本构模型的参数
颗粒材料的应力-应变行为可以用亚塑性本构关系建模。简要介绍了轴对称情况下的亚塑性模型，并详细描述了其参数的确定过程。结果表明，对于几种砂和一种砾石，亚塑性模型的所有参数都与颗粒集合体的粒度特性密切相关。为了验证所提出的程序，对一些元件试验进行了重新计算。版权所有©1999 John Wiley&；有限公司。
