Bernhardt Freiberg 1 Position, tasks and structure of particle size analysis Today the concept of particle size analysis is that of a special field of particle measurement technology, which in turn is part of particulate technology.

Mechanische Eigenschaften und Versagensmechanismen offenzelliger Aluminiumschaum-Strukturen. Mechanical properties and failure behaviour of open cell Aluminium foam structures. Fleck, Claudia Bührig-Polaczek, Andreas. In the context of the development of new and innovative concepts for lightweight design, metal foams have awakened the interest of research institutes and industry for some considerable amount of time, as they provide almost isotropic mechanical behaviour and superior temperature stability in comparison with competing cellular materials.
Furthermore, the cellular structure of the metal foams provides a number of functional properties in addition to their ability to carry mechanical load, such as vibration dampening and efficient energy absorption.
The investment casting route in combination with additive layer manufacturing of the casting moulds allows the manufacture of new aluminium based metal foam structures with an almost free design of the of cells and struts geometry.
The optimization of the effective properties of the metal foam structures through the fine-tuning of structural and material-specific parameters requires a deep understanding of the complex interaction structure and effective properties of the material.
In view of the above, this thesis investigates the microstructure- and topology-related failure mechanisms and studies their impact on the effective properties of open-cell investment-cast aluminium foams under uniaxial compression.
Furthermore, three different alloys Al To study the influence of the model parameters, two different tools are introduced, namely model reduction and parameter identification.
Model reduction is used to study the sensitivity of the parameters and to accelerate the solution procedure. Multiple ways to construct a projection basis are discussed and reviewed.
For parameter identification, an optimization framework for the free boundary problem is derived. Therefore a gradient algorithm in combination with an adjoint formulation is used.
The models are compared to several experimental data and different mathematical aspects of the problem are tested, too. The results show that it is possible to reproduce the experimental data. It is further shown that a nonlinear pressure drop, often arising in cake filtration, can be explained by the model without considering compression of the cake. Hendrik Eike Nolte Languange: Sierke Verlag Format Available: Incorporation of particular components with specialized properties allows one to tailor the end product's properties.
For instance, the sensitivity, burning behavior, thermal or mechanical properties or stability of energetic materials can be affected and even controllably varied through incorporation of such ingredients. This book examines particle technologies as applied to energetic materials such as propellants and explosives, thus filling a void in the literature on this subject. Following an introduction covering general features of energetic materials, the first section of this book describes methods of manufacturing particulate energetic materials, including size reduction, crystallization, atomization, particle formation using supercritical fluids and microencapsulation, agglomeration phenomena, special considerations in mixing explosive particles and the production of nanoparticles.
The second section discusses the characterization of particulate materials. Techniques and methods such as particle size analysis, morphology elucidation and the determination of chemical and thermal properties are presented.
