Elastic Fields of a Nonhomogeneous Half-Space Subject to an Inclined Circular Load

الملخص EN

The paper examines the elastic fields of displacements and stresses for a nonhomogeneous elastic half-space where the elastic parameters have a linear variation over a finite depth beyond which it is constant.

The circular loading area is subjected to a uniform inclined load.

The numerical method is developed by applying the fundamental solution of a layered elastic solid and integrating numerically it over the loading area.

As a result, only the loading area needs to be discretized in using the proposed numerical method.

Numerical examples of calculation of displacements are conducted, and excellent agreement with the existing closed-form solutions is obtained.

The results obtained are used to understand the elastic fields induced by different types of loads in a nonhomogeneous medium.
