Bousinesq场和泡场的叠加组合充分描述了凹陷地下的应力场。一种基于能量守恒的方法被用来预测的起泡场的强度的值在实验确定的机械参数，硬度，剪切模量和泊松比。用150°和90°圆锥压入铜和氧化铝的实验结果与预测值进行了比较。讨论了压痕法在氧化铝样品中引起断裂的意义。
A superposed combination of the Bousinesq and blister field adequately describes the stress field in an indented subsurface. A method based on energy conservation is used to predict the value of the strength of the blister field in terms of experimentally determinable mechanical parameters, hardness, shear modulus and Poisson's ratio. The predicted values are compared with those measured experimentally by indenting copper and alumina by 150° and 90° cones. The implications of fracture induced in alumina samples by indentation are discussed.
