Abstract

This paper examines non-homogeneous geo-material halfspaces under the axisymmetric indentation of a circular rigid plate. A multilayered model is proposed to approximate arbitrary variations of the elastic parameters in geo-materials with depth. The non-homogeneous geo-material halfspaces can have variable shear modulus and Poisson's ratio with depth. Numerical verification is performed for the contact problem of a non-homogeneous halfspace with variable shear modulus and constant Poisson's ratio. Results illustrate the effects of material inhomogeneity on the elastic fields of a non-homogeneous halfspace.

圆形刚性板轴对称压入下非均质土工材料半空间的精确弹性场

本文研究了圆形刚性板轴对称压痕作用下的非均质土工材料半空间。本文提出了一个多层模型，以近似反映土工材料弹性参数随深度的任意变化。非均质土工材料的半空间可以具有随深度变化的剪切模量和泊松比。对剪切模量可变、泊松比不变的非均质半空间的接触问题进行了数值验证。结果说明了材料不均匀性对非均质半空间弹性场的影响。

期刊介绍： Mechanics Research Communications publishes, as rapidly as possible, peer-reviewed manuscripts of high standards but restricted length. It aims to provide: • a fast means of communication • an exchange of ideas among workers in mechanics • an effective method of bringing new results quickly to the public • an informal vehicle for the discussion • of ideas that may still be in the formative stages The field of Mechanics will be understood to encompass the behavior of continua, fluids, solids, particles and their mixtures. Submissions must contain a strong, novel contribution to the field of mechanics, and ideally should be focused on current issues in the field involving theoretical, experimental and/or applied research, preferably within the broad expertise encompassed by the Board of Associate Editors. Deviations from these areas should be discussed in advance with the Editor-in-Chief.
