- Description
- There exist many problems in the offshore geotechnical setting which necessitate a dynamic analysis or a consolidation analysis. In recent years literature on this topic has been dominated by the application of Finite Element Methods to solving such problems and addressing the inherent shortcomings associated with their use. These issues include, but are not limited to, the occurrence of mesh distortion in problems involving large deformations and the inability to adequately capture discontinuities. The intrinsic nature of meshfree methods, however, makes them a more appropriate means of solving offshore geotechnical problems. This study presents a robust Maximum-Entropy Meshless method for nonlinear analysis of offshore problems in which the effect of time-dependent behaviour cannot be ignored. The Generalised-α time integration scheme and the Backward-Euler method are respectively employed for dynamic analysis and coupled analysis of such problems. The applicability of this meshless method is presented by studying the undrained soil behaviour under a circular footing subjected to dynamic loading as well as static loading.
