本文研究了圆柱形冲头与刚性基底上的粘性弹性层或薄膜的接触问题。将经典的赫兹接触假设与断裂力学工具相结合来求解接触问题。通过引入Dugdale-Barenblatt模型，解决了接触边缘的奇异性。精确的控制方程，从而获得解决的半分析技术，采用切比雪夫多项式。我们还扩展了有用的JKR近似压痕的弹性层作为一个特殊的情况下，我们的一般解决方案。
We investigate the contact of a cylindrical punch with an adhesive elastic layer or film bonded to a rigid substrate. The classical assumption of Hertzian contact are coupled with tools of fracture mechanics to resolve the contact problem. The contact edge's singularity is resolved by introducing a Dugdale-Barenblatt model for the adhesive zone extending in front of the contact region. Exact governing equations so obtained are solved by a semi-analytical technique employing Chebyshev polynomials. We also extend the useful JKR approximation to the indentation of elastic layers as a particular case of our general solution.
