Theoretical and experimental techniques to estimate mechanical properties of thin films are studied. The studies are summarized as follows :(1)By appplying the Hertzian contact theory and assuming a stress field in the film-coated body, an approximate solution of elastic contact problem between film-coated bodies is proposed. By using the solution, a technique to estimate Young's modulus and Poisson's ratio of thin films is proposed and applied to an experimental model.(2)A technique to estimate Yielding point and work hardening ratio of thin films is proposed using the elasto-plastic finite element method.(3)The bending theory of a muti-laminate subjected to thermal load is proposed. By using this theory, Young's modulus and Poisson's ratio of thin films are estimated and compared with the corresdponding experimental values.

研究了估计薄膜机械性能的理论和实验技术。研究总结如下：（1）通过对赫兹的接触理论进行应用，并假设在膜包被的身体中存在应力场，提出了薄膜包被的身体之间弹性接触问题的近似解决方案。通过使用解决方案，提出了一种估计Young的模量和泊松比的技术，并应用于实验模型。（2）提出了一种估算薄膜的屈服点和工作硬化比率的技术，该技术是使用Elasto-Plasto-Plastic有限元方法提出的。通过使用该理论，估算了Young的模量和薄膜的Poisson比率，并将其与corsdponding实验值进行了比较。
