Abstract

This paper focuses on presentation of waves phenomena that occur during propagation of disturbance in continuous incompressible hyperelastic structures, described with elastic potential. Numerical analysis demonstrated differences during the propagation of disturbances in the commonly used model of Mooney-Rivlin material compared to less popular Zahorski material. The obtained result is also likely to contribute to development of new forms of practical application of nonlinear rubber and rubber-like materials for technological solutions, including those used in the broadly understood construction sector.

Abstract

Simplification of the design of Mechanically Stabilized Earth wall structures (MSE wall or MSEW) is now an important factor that helps us not only to save a time and costs, but also to achieve the desired results more reliably. It is quite common way in practice, that the designer of a section of motorway or railway line gives order for design to a supplier of geosynthetics materials. However, supplier company has experience and skills, but a general designer does not review the safety level of design and its efficiency, and is simply incorporating into the overall design of the construction project. Actually, large number of analytical computational methods for analysis and design of MSE walls or similar structures are known. The problem of these analytical methods is the verification of deformations and global stability of structure. The article aims to clarify two methods of calculating the internal stability of MSE wall and their comparison with FEM numerical model. Comparison of design approaches allows us to draft an effective retaining wall and tells us about the appropriateness of using a reinforcing element.
