对理想土壤运动学的现有理论的考察表明，这些理论中没有一个能为理论的进一步发展提供真正令人满意的基础。本文根据材料各向同性、土的不可压缩性和在某些临界平面上剪切变形的观点，提出了理想土平面变形的理论。作为这些假设的自然结果，发现土壤中的应变率既取决于应力，也取决于应力率。该理论适用于一个半无限大规模的土壤由一个平坦光滑的刚性冲头压痕的问题。
An examinationof existing theories of the kinematics of ideal soils suggests that none of these yet provide a really satisfactory basis for further developments of the theory. A theory is proposed, for plane deformations of ideal soils, which is based on the postulates of material isotropy, soil incompressibility, and the idea that deformation occurs by shear on certain critical planes. It is found as a natural consequence of these assumptions that the strain-rate in the soil is dependent on the stress-rate as well as on the stress. The theory is applied to the problem of indentation of a semi-infinite mass of soil by a flat smooth rigid punch.
