得到了沿裂纹面任意位置有部分接触的便士形裂纹的柔度张量和电阻率贡献张量，包括接触大小和距离中心的距离。这一结果是对裂纹面之间有接触的“粗糙”裂纹进行建模的第一步。应用于多个裂纹，我们的结果产生“调整”，对于接触的存在，裂纹密度值的接触参数。在电导率的情况下也得到了类似的结果。
Compliance and resistivity contribution tensors of a penny-shaped crack having a partial contact of arbitrary location along crack faces are found, in terms of contact size and its distance from the center. This result is a first step towards modeling of “rough” cracks having contacts between crack faces. Being applied to multiple cracks, our results yield the “adjusted”, for the presence of contacts, value of crack density in terms of contact parameters. Similar results are obtained in the context of conductivity.
