Mechanical behaviour

Introduction to shock & vibration gives an introduction to vibration through a description of the most common mechanical parameters leading to the behaviour of simple mass spring systems. Furthermore the different types of signals and their description is treated and the conversion between the different parameters is described mathematically and graphically. Finally the measurement units are defined.

In this thesis, a numerical model with detailed reaction mechanism which is tailored for studying the behaviour of combustion of natural gas has been introduced and validated with available experimental data. The numerical model attempts to comprehensively simulate the physical conditions (temperature and pressure), equivalent ratio, and fuel dilution and strain rate effect in the laminar flames.

The study "Studies on film forming corrosion inhibitors on aluminium alloy, AA2024-T3" presents key aspects of the film forming behaviour of the selected inhibitors and the test methods used to evaluate the inhibitor induced films in a chloride solution. This study also aims to provide significant insights to the film tenacity, the influence of the molecular structure as well as the film stability in the absence of inhibitors to provide a deeper understanding of the film forming and film breakdown mechanisms.

The nasal route for drug administration has the potential for local and systemic delivery of a wide variety of therapeutics. Nasal spray drug delivery has the potential to administer drugs to the bloodstream, avoiding the use of painful needles. While there is great potential, studies in the area are limited and somewhat conflicting. This study aimed to support the improvement of nasal drug delivery through experimental work on a model nasal cavity and through experimental characterisation of nasal spray behaviour. Four different brands of nasal spray were investigated.

Composite materials have gained traction in the world today and are becoming of common use in industrial and specialized applications in general due to their flexible nature that involves mixing through layers or matrixes the components of various substances and therefore, a percentage of each substance’s physical properties.

When boron carbide is used as a neutron absorber in nuclear power plants, large quantities of helium are produced. To simulate the gas behaviour, helium implantations were carried out in boron carbide. The samples were then annealed up to 1500 °C in order to observe the influence of temperature and duration of annealing.

The mechanism of corrosion inhibition was explored and supplemented by adsorption and surface morphological studies. Quantum mechanical investigations on corrosion behaviour of compounds were also conducted and satisfying correlation was noticed between the results of corrosion measurement methods and quantum mechanical evaluations.

Considering accurate constitutive models is of the utmost importance when capturing the mechanical response of soft tissue and biomedical materials under physiological loading conditions. This paper investigated the behaviour of porcine myocardium in passive rested hearts. This was done by applying biaxial loads on the myocardium.

In yeast, a sudden transition from glucose limitation to glucose excess leads to a new steady state at increased metabolic fluxes with a sustained decrease in the ATP concentration. Although this behaviour has been rationalized as an adaptive metabolic strategy, the mechanism behind it remains unclear.
