This book was released on 2014-10-01 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work furthers the overall understanding of a 3w-measurement, by considering previously unexamined macroscopic influence factors within measurement by Finite Element simulations (FES). Moreover, new measuring configurations are developed to determine (an)isotropic thermal conductivities of nanoscale samples. Since no analytic solutions are available for these configurations, a new evaluation methodology is presented to determine emergent thermal conductivities by FES and Neural Networks.
Book Synopsis Phase-field Modeling of Multi-domain Evolution in Ferromagnetic Shape Memory Alloys and of Polycrystalline Thin Film Growth by : Christian Mennerich
Download or read book Phase-field Modeling of Multi-domain Evolution in Ferromagnetic Shape Memory Alloys and of Polycrystalline Thin Film Growth written by Christian Mennerich and published by KIT Scientific Publishing. This book was released on 2014-05-13 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The phase-field method is a powerful tool in computer-aided materials science as it allows for the analysis of the time-spatial evolution of microstructures on the mesoscale. A multi-phase-field model is adopted to run numerical simulations in two different areas of scientific interest: Polycrystalline thin films growth and the ferromagnetic shape memory effect. FFT-techniques, norm conservative integration and RVE-methods are necessary to make the coupled problems numerically feasible.

Book excerpt: With the advent of high performance computing, the application areas of the phase-field method, traditionally used to numerically model the phase transformation in metals and alloys, have now spanned into geoscience. A systematic investigation of the two distinct scientific problems in consideration suggest a strong influence of interfacial energy on the natural and induced pattern formation in diffusion-controlled regime.
Book Synopsis Modelling the Plastic Deformation of Iron by : Zhiming Chen
Download or read book Modelling the Plastic Deformation of Iron written by Zhiming Chen and published by KIT Scientific Publishing. This book was released on 2014-07-31 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1/2111 screw dislocations in bcc iron are studied by atomistic simulations. An analytical yield criterion captures correctly the non-Schmid plastic behavior. A model Peierls potential develops a link between the atomistic modeling at 0 K and the thermally activated dislocation motion. All predicted features agree well with experimental observations. This work establishes a consistent bottom-up model that provides an insight into the microscopic origins of the plastic behavior of bcc iron.
Book Synopsis Deformation and Fracture Properties of the Soft Magnetic Composite Somaloy 700 3P on Different Length Scales by : Schwark, Tabea Gisela
Download or read book Deformation and Fracture Properties of the Soft Magnetic Composite Somaloy 700 3P on Different Length Scales written by Schwark, Tabea Gisela and published by KIT Scientific Publishing. This book was released on 2018-07-09 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soft Magnetic Composites (SMCs) typically consist of large iron particles coated with a fairly thin inorganic layer. The combination of soft particles with a brittle layer causes, however, a rather poor mechanical behaviour of the SMCs. The particle boundaries of the specific SMC Somaloy 700 3P can be classified into four different types according to the complexity of their layers. Tests on both micro- and macroscale showed that the particle-boundary interface is critical in terms of failure.
Book Synopsis Fatigue of Micro Molded Materials - Aluminum Bronze and Yttria Stabilized Zirconia by : Kennerknecht, Tobias
Download or read book Fatigue of Micro Molded Materials - Aluminum Bronze and Yttria Stabilized Zirconia written by Kennerknecht, Tobias and published by KIT Scientific Publishing. This book was released on 2014-12-04 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Custom built setups were developed to investigate micro samples during quasistatic and cyclic testing in tension, compression and bending. Micro molded CuAl10Ni5Fe4-samples showed similar fatigue behavior compared to macroscopic samples due to both the sample size and microstructure being scaled down with the manufacturing process. Results from cyclic three-point bending tests on micro molded 3Y-TZP suggested that a minimum crack extension is necessary to develop cyclically degradable shielding.
Book Synopsis The Effects of Internal Stress and Lithium Transport on Fracture in Storage Materials in Lithium-Ion Batteries by : Klinsmann, Markus
Download or read book The Effects of Internal Stress and Lithium Transport on Fracture in Storage Materials in Lithium-Ion Batteries written by Klinsmann, Markus and published by KIT Scientific Publishing. This book was released on 2016-03-08 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fracture of storage particles is considered to be one of the major reasons for capacity fade and increasing power loss in Li-ion batteries. In this work, we tackle the problem by merging a coupled model of mechanical stress and diffusion of Li-ions with a phase field description of an evolving crack. The novel approach allows us to study the evolution of the Li concentration together with the initiation and growth of a crack in an arbitrary geometry and without presuming a specific crack path.
