利用Sneddon对刚性轴对称凸模与弹性半空间之间的弹性接触的分析结果，证明了接触刚度、接触面积和弹性模量之间存在简单的关系，这种关系不依赖于凸模的几何形状。这种关系的普遍性对于使用负载和深度感测压痕技术测量机械性能以及原子力显微镜中遇到的小接触区域的测量具有重要意义。
Results of Sneddon's analysis for the elastic contact between a rigid, axisymmetric punch and an elastic half space are used to show that a simple relationship exists among the contact stiffness, the contact area, and the elastic modulus that is not dependent on the geometry of the punch. The generality of the relationship has important implications for the measurement of mechanical properties using load and depth sensing indentation techniques and in the measurement of small contact areas such as those encountered in atomic force microscopy.
