Numerical analysis of non-linear large-strain consolidation and filling [PDF]
Computers & Structures, 1992 Finite strain consolidation and filling of soft sediments at high water level is a challenging problem because of its highly non-linear physical and mathematical aspects. Several numerical schemes designed for this problem are presented as well as simple numerical improvements for a better handling of the extremely high variations of the material ...

An analytical and experimental study of large strain soil consolidation
, 1979 This thesis is concerned with large strain soil consolidation and a large portion of the work is devoted to the theoretical development in modelling this phenomenon. An experimental programme based on a specially designed oedometer is also included. The governing equations are formulated in Chapter 2, where both the material and the space coordinates ...

Large strain consolidation with time and distance dependent boundary conditions
, 2021 Clogging is often observed in the improvement of dredged fills using the vacuum pressure combined prefabricated vertical drains. Due to the clogging at the drain, vacuum pressure needs some time to achieve the target value, and the magnitude of the ...
