| 英文摘要 | In this paper, an efficient calculation method based on discrete Fourier transformation is developed for evaluating elastic load induced elastic deformation fields of film-substrate system. Making use of 2D discrete Fourier transformation, the elastic fields induced by Hertz load is harvested in frequency domain, and the displacement and stress fields across the interface are enforced to satisfy the elasticity conditions for each Fourier modes. Given arbitrary distributed stress field at free surface plane of the three types of film-substrate systems, unique resultant elastic field within the can be harvested. Hertz load of half space, elastic film on elastic substrate, elastic film on rigid substrate system and elastic film-substrate system with three types of imperfect interface models are investigated: (1) the spring-like imperfect interface model which can be described as: U-k(f)vertical bar(zf=-h) - u(k)(s)vertical bar(zs=0) = K-T sigma(kz) and u(z)(f)vertical bar(zf=-h) - u(z)(s)vertical bar(zs=0) = K-N sigma(zz); (2) the dislocation-like interface model, where interface displacement and stress components relation can be described as: u(i)(f)vertical bar(zf=0) = k(ij)(u) u(i)(s)vertical bar(zs=0) and sigma(f)(iz)vertical bar(zf=0) = sigma(s)(iz)vertical bar(zs=0); (3) the force-like interface model, where interface displacement and stress components relation can be described as: u(i)(f)vertical bar(zf=0) = u(i)(s)vertical bar(zs=0) and sigma(f)(iz)vertical bar(zf=0) = k(ij)(t) sigma(s)(iz)vertical bar(zs=0) respectively. Finally, several simulation examples are performed for verification of the reliability and efficiency of the proposed semi-analytical methods. (C) 2020 The Authors.
