The method of derivation of multi-dimensional elastic-plastic increment constitutive model under general loading in the stress space is generalized into strain space. In the strain space, united loading-unloading criterions for elastic-perfectly plastic, hardening and softening materials are discussed.
5.将推导应力空间中一般荷载下的多维增量本构模型的一种途径推广到应变空间;讨论了应变空间中的加卸载准则，推导了在应变空间中描述的等向硬化/软化岩土材料一般荷载下的弹塑性增量本构关系的统一形式;并将在应力空间中建立的等向硬化、随动硬化和理想弹塑性岩土材料的多维增量本构关系的一般公式推广到应变空间中。
