| 英文摘要 | The interaction between layered contacts and material heterogeneity is a fundamental topic in solid mechanics, providing valuable insights into material damage and strengthening mechanisms. Based on micromechanics, this study presents a robust and effective approach to deal with such complexities through an inclusion-based method. The closed-form Eshelby tensors for cuboidal inclusion in a semi-infinite medium are derived, unifying the expressions for both the interior and exterior stress fields. The analytical solutions are presented in a concise notation that integrates seamlessly with Fast Fourier Transform (FFT) algorithms, facilitating efficient and accurate numerical computations. The Numerical Equivalent Inclusion Method (NEIM) is employed to model material heterogeneity and analyze contact behaviors in non-homogeneous half-space models with arbitrary inhomogeneities. Benchmark examples validate the analytical solutions and numerical implementation, demonstrating the effectiveness of the present method in modeling the influence of material heterogeneity in layered contact problems. The proposed numerical scheme offers a powerful and versatile tool for contact analyses involving material heterogeneities. |
