A model for the time dependent behaviour of rock joints
… thesis is a theoretical investigation into the time-dependent behaviour of rock joints. Much of the research work that has been conducted to date in the area of finite element analysis has been involved with the development of special elements to deal with these discontinuities. A comprehensive …

An experimental study on time-dependent behaviour of reconstituted clayey soils in 1D and triaxial compression
… of geotechnical structures against the time-dependent strength-deformation behaviour of soils relies on the knowledge acquired from laboratory and field experiments. Therefore, the focus of this research is to experimentally investigate the role of stress history, soil properties and …

Creep behaviour of shallow foundations on sand and its implication to soil–structure interaction
… a method that can explicitly account for the time-dependent behaviour of footings on sand in a realistic manner and to explore its potential use in practice. To achieve the goal, the research included three parts, starting with understanding the time-dependent behaviour of sand that derives …

Zum zeitabhängigen Verhalten elektrochemischer und morphologischer Kenngrößen bei der chloridinduzierten Korrosion von Stahl in Beton
… concrete this thesis aims at the analysis of the time dependent behaviour of electro-chemical and morphological parameters of the macro-cell anode being the location of active metal dissolution. As a result of electro-chemical investigations time dependent and statistically firm free corrosion …

Queueing models for call centres
… call centres, i.e. multi-server systems with time-dependent arrival rates, general service time distribution and state-dependent abandonments on arrival (balking). The discrete-time modelling approach which has previously been used for modelling the time-dependent behaviour of multi-server …

Theoretical studies of strongly interacting fine particle systems
A theoretical analysis of the time dependent behaviour of a system of fine magnetic particles as a function of applied field and temperature was carried out. The model used was based on a theory assuming Neel relaxation with a distribution of particle sizes. This theory predicted a linear variation …

Time dependent flexural analysis of reinforced concrete members
… in the construction industry in the world. Time dependent behaviour of concrete is the major concern for the structural engineers due to its significant effect in the long term serviceability and durability. Reinforced concrete (RC) members are prone to the effect of time dependent …

Hydrodynamic, acoustic, and electrical characteristics of underwater spark discharges initiated by different mechanisms
… model allowed for accurate description of the time-dependent behaviour of different parameters during the underwater spark discharge process. The obtained results are important for optimising the circuit parameters for generation of tailored acoustic impulses for different practical …

Study of the time-dependent rheological behaviour of lead-free solder pastes and flux mediums used for flip-chip assembly applications
… This means that the paste flow and deformation behaviour is very important in defining the printing performance of any solder paste. In order to understand rheological phenomena associated with the flow of solder pastes, it is necessary to understand time dependent rheological behaviour. Such …

Time dependence in fine-particle systems
The time dependent behaviour of the magnetisation of a non interacting ensemble of Stoner-Wohlfarth fine particles has been investigated. The particles typically represent the elongated single domain ferromagnetic particles that have widespread application in the magnetic recording industry. The …

Mechanical behaviour of Clay-Shales (Argille Scagliose) and implications on the design of tunnels
… particular attention to the development of large time-dependent deformations. These deformations may develop either during the construction stage, causing instabilities of the tunnel face and unsafe working conditions, or remain hidden during the “short-term”, thus leading to complex problems when …

Active contraction of the left ventricle with cardiac tissue modelled as a micromorphic medium
… due in part to the anisotropic, non-linear and time-dependent behaviour as well as the complex hierarchical material structure of biological tissues. In general, cardiac tissue is treated as a non-linear elastic and incompressible material. Most computational studies employ the theories of …

Theoretical studies of the mid-latitude ionosphere
… remain subsonic for realistic conditions. The time-dependent behaviour of He+ under sunspot minimum conditions is investigated in Chapter IV. This is achieved by numerical solution of the 0+, H+ and,He+ continuity and momentum equations, treating He+ as a minor ion with 0+ , H+ as major ions. …

Modelling of deep tunnel behaviour in clay
… i.e. a continually increasing volume loss with time, and possible collapse after a 'stand-up' time. A range of parameters likely to influence the time dependent deformation behaviour at an unsupported tunnel face was investigated in a number of small scale model tunnel tests. The tests were …
