Stress disturbance on the cyclic behavior of soils and its impact on geotechnical structures
… loading, a large number of cyclic triaxial tests were carried out to investigate the cyclic deformation behavior of typical sand and clay samples. The tests on clay are performed under undrained condition to reveal the axial strain and excess pore water pressure accumulations, and the tests …

The Response of Buildings to Excavation-Induced Ground Movements
The results of physical model tests and field observations are combined with the results of parametric studies, and together they are used to provide a background for developing guidelines for controlling building damage and to develop a procedure for estimating building damage due to …

A New Method to Predict Vessel Capsizing in a Realistic Seaway
… this technique can also be used to guide physical model tests or computer simulation studies to focus on critical vessel and environmental conditions which may result in dangerously large motion amplitudes. Extensive comparitive results are included to demonstrate the practical usefulness …

Experimentelle Untersuchungen zur Verformungsakkumulation und Tragfähigkeitsreduktion von zyklisch belasteten Pfählen
… For this purpose, a program of experimental tests has been carried out, which for the case of the laterally loaded single pile foundation was based on physical model tests in two different scales. The validity of the hypothesis of independence of the deformations of the order of different …

An integrated approach to damage ship survivability assessment
… based on free-mass-on-potential-surface (FMPS) model. Non-linear treatment of the effects of cargo shift or floodwater motions on the overall ship dynamic behaviour. The underlying modelling has been explained by rigorous derivation of all the relevant equations from first principles. Validity …

Salinity Transport in a Finite-Volume Sigma-Layer Three-Dimensional Model
The objective of this study was to develop a 3-D model for The Pontchartrain Estuary that was capable of long-term mass conservative simulation of salinities. This was accomplished in a multi-stage approach involving: a physical model of salinity exchange through a pass; a 3-D FVCOM model of the …

The hybrid of floating stone column by numerical and physical evaluation
… An elastic-perfectly plastic constitutive soil model relation based on the Mohr-Coulomb criterion was utilized to predict the behaviour of soft clay strengthen by stone column. Response Surface Methodology (RSM) was used to optimize the hybrid stone column size with the Design-Expert 6.0.4 …

Micro-modelling of wave fields
Physical models transfer part of the natural world into controlled laboratory conditions without the oversimplifying assumptions required by numerical models. However large scale hydraulic facilities are associated with large expenditure, require a high level of preparation, while at the same time …

Simulation of ship-ice collision dynamics.
… The task of developing effective numerical models for studying the collision process has been hampered by the complexity of the physical interaction mechanisms. The present research considers the nonlinear and dynamic character of this problem. A method for time-domain simulation of …

Investigation of the critical specific gravity for cables and pipelines during various backfilling and installation processes
… ploughing were investigated by means of scaled physical model tests. The purpose of the investigation was to optimise the specific gravity (SG) of pipelines and cables to minimise flotation or movement during installation. The issues under considerations were the flotation of pipelines/cables in …

Movements around a tunnel in two-layer ground
… of investigation were geotechnical centrifuge model testing and finite element analysis using the 3-Surface Kinematic Hardening (3-SKH) model, an elasto-plastic soil model implemented in the finite element program CRISP at City University, London. Both methods use effective stress path …
