为作者及其同事提出的砂土循环行为的应变空间多机制模型提供了理论支持(Iai et al., 1992)。先前提出的模型是平面应变机制。通过将平面应变机制叠加在任意方向的轴周围，本研究表明该模型可以扩展到三维空间。研究还表明，该模型满足客观性，这对于现实的本构模型至关重要。
A theoretical backup is offered for the strain space multiple mechanism model of cyclic behavior of sand presented by the author and his colleagues (Iai et al., 1992). The model presented previously was of a plane strain mechanism. By superposing the plane strain mechanisms around axes of arbitrary orientations, the present study demonstrates that the model can be extended into the three dimensional space. The study also shows that the model satisfies the objectivity, which is essential to a realistic constitutive model.
