Yield Surface-Based Solution for Evaluating Embedded Chain Behavior

Abstract

This paper establishes a soil resistance yield surface for chain links embedded in clay using three-dimensional finite element analysis that considers realistic chain geometries and the effect of embedment depth. The derived yield surface and its associated flow rule are used to develop a new analytical solution for evaluating embedded chain behavior. Unlike existing approaches that decouple axial and normal resistances to embedded chains by assuming a constant friction coefficient, the proposed solution captures the interaction between three-dimensional soil resistance components through the yield surface formulation. The new solution is validated against published experimental data and fur..
